e. When operating a power tool outdoors, use an  
extension cord suitable for outdoor use. Use of a cord  
suitable for outdoor use reduces the risk of electric shock.  
General safety rules  
WARNING. Read all instructions. Failure to follow all  
instructions listed below may result in electric shock,  
fire and/or serious injury. The term “power tool” in all of  
the warnings listed below refers to your mains operated  
(corded) power tool or battery operated (cordless)  
power tool.  
3. Personal safety  
a. Stay alert, watch what you are doing and use  
common sense when operating a power tool. Do  
not use a power tool while you are tired or under the  
influence of drugs, alcohol or medication. A moment of  
inattention while operating power tools may result in  
serious personal injury.  
Save these instructions  
1. Work area  
a. Keep work area clean and well lit. Cluttered and dark  
areas invite accidents.  
b. Use safety equipment. Always wear eye protection.  
Safety equipment such as dust mask, non-skid  
b. Do not operate power tools in explosive  
atmospheres, such as in the presence of flammable  
liquids, gases or dust. Power tools create sparks which  
may ignite the dust or fumes.  
safety shoes, hard hat, or hearing protection used for  
appropriate conditions will reduce personal injuries.  
c. Avoid accidental starting. Ensure the switch is in the  
off position before plugging in. Carrying power tools with  
your finger on the switch or plugging in power tools that  
have the switch on invites accidents.  
c. Keep children and bystanders away while  
operating a power tool. Distractions can cause you to  
lose control.  
d. Remove any adjusting key or wrench before turning  
the power tool on. A wrench or a key left attached to  
a rotating part of the power tool may result in personal  
injury.  
2. Electrical safety  
a. Power tool plugs must match the outlet. Never  
modify the plug in any way. Do not use any adapter  
plugs with earthed (grounded) power tools. Unmodified  
plugs and matching outlets will reduce risk of electric  
shock.  
e. Do not overreach. Keep proper footing and balance at  
all times. This enables better control of the power tool in  
unexpected situations.  
b. Avoid body contact with earthed or grounded  
surfaces such as pipes, radiators, ranges and  
refrigerators. There is an increased risk of electric shock  
if your body is earthed or grounded.  
f. Dress properly. Do not wear loose clothing or  
jewellery. Keep your hair, clothing and gloves away from  
moving parts. Loose clothes, jewellery or long hair can be  
caught in moving parts.  
c. Do not expose power tools to rain or wet conditions.  
Water entering a power tool will increase the risk of  
electric shock.  
g. If devices are provided for the connection of dust  
extraction and collection facilities, ensure these are  
connected and properly used. Use of these devices  
can reduce dust related hazards.  
d. Do not abuse the cord. Never use the cord for  
carrying, pulling or unplugging the power tool.  
Keep cord away from heat, oil, sharp edges or moving  
parts. Damaged or entangled cords increase the risk of  
electric shock.

4. Power tool use and care  
Additional safety rules for laser lights  
a. Do not force the power tool. Use the correct power tool  
for your application. The correct power tool will do the job  
better and safer at the rate for which it was designed.  
The laser light/laser radiation used in the GMC REDEYE®  
system is Class 2 with maximum output of 1mW and a  
wavelength of 650nm. These lasers do not normally present  
an optical hazard, although staring at the beam may cause  
flash blindness.  
b. Do not use the power tool if the switch does not turn  
it on and off. Any power tool that cannot be controlled  
with the switch is dangerous and must be repaired.  
WARNING. Do not stare directly at the laser beam.  
c. Disconnect the plug from the power source before  
making any adjustments, changing accessories, or  
storing power tools. Such preventive safety measures  
reduce the risk of starting the power tool accidentally.  
A hazard may exist if you deliberately stare into the beam.  
Please observe all safety rules as follows:  
The laser shall be used and maintained in accordance  
with the manufacturer’s instructions.  
d. Store idle power tools out of the reach of children  
and do not allow persons unfamiliar with the power  
tool or these instructions to operate the power tool.  
Power tools are dangerous in the hands of untrained  
users.  
Never aim the beam at any person or an object other  
than the workpiece.  
The laser beam shall not be deliberately aimed at  
personnel and shall be prevented from being directed  
towards the eye of a person for longer than 0.25s.  
e. Maintain power tools. Check for misalignment or  
binding of moving parts, breakage of parts and  
any other condition that may affect the power tools  
operation. If damaged, have the power tool repaired  
before use. Many accidents are caused by poorly  
maintained power tools.  
Always ensure the laser beam is aimed at a sturdy  
workpiece without reflective surfaces, i.e. wood or rough  
coated surfaces are acceptable. Bright shiny reflective  
sheet steel or the like is not suitable for laser use as  
the reflective surface could direct the beam back at the  
operator.  
f. Keep cutting tools sharp and clean. Properly  
maintained cutting tools with sharp cutting edges are less  
likely to bind and are easier to control.  
Do not change the laser light assembly with a different  
type. Repairs must only be carried out by the laser  
manufacturer or an authorised agent.  
g. Use the power tool, accessories and tool bits etc.,  
in accordance with these instructions and in the  
manner intended for the particular type of power  
tool, taking into account the working conditions and  
the work to be performed. Use of the power tool for  
operations different from those intended could result in a  
hazardous situation.  
5. Service  
a. Have your power tool serviced by a qualified repair  
person using only identical replacement parts. This  
will ensure that the safety of the power tool is maintained.  
CAUTION. Use of controls or adjustments or performance  
of procedures other than those specified herein may result  
in hazardous radiation exposure.

When the blade is pinched or bound tightly by the kerf  
closing down, the blade stalls and the motor reaction  
drives the unit rapidly back toward the operator;  
Additional safety rules for circular saws  
DANGER  
a. Keep hands away from cutting area and the blade. Keep  
your second hand on auxiliary handle, or motor housing.  
If both hands are holding the saw, they cannot be cut by  
the blade.  
If the blade becomes twisted or misaligned in the cut, the  
teeth at the back edge of the blade can dig into the top  
surface of the wood causing the blade to climb out of the  
kerf and jump back toward the operator.  
b. Do not reach underneath the workpiece. The guard  
cannot protect you from the blade below the workpiece.  
Kickback is the result of saw misuse and/or incorrect  
operating procedures or conditions and can be avoided by  
taking proper precautions as given below.  
c. Adjust the cutting depth to the thickness of the workpiece.  
Less than a full tooth of the blade teeth should be visible  
below the workpiece.  
a. Maintain a firm grip with both hands on the saw and  
position your arms to resist kickback forces. Position your  
body to either side of the blade, but not in line with the  
blade. Kickback could cause the saw to jump backwards,  
but kickback forces can be controlled by the operator, if  
proper precautions are taken.  
d. Never hold piece being cut in your hands or across  
your leg. Secure the workpiece to a stable platform. It is  
important to support the work properly to minimize body  
exposure, blade binding, or loss of control.  
e. Hold power tool by insulated gripping surfaces when  
performing an operation where the cutting tool may  
contact hidden wiring or its own cord. Contact with a “live”  
wire will also make exposed metal parts of the power tool  
“live” and shock the operator.  
b. When blade is binding, or when interrupting a cut for any  
reason, release the trigger and hold the saw motionless  
in the material until the blade comes to a complete  
stop. Never attempt to remove the saw from the work  
or pull the saw backward while the blade is in motion  
or kickback may occur. Investigate and take corrective  
actions to eliminate the cause of blade binding.  
f. When ripping always use a rip fence or straight edge  
guide. This improves the accuracy of cut and reduces the  
chance of blade binding.  
c. When restarting a saw in the workpiece, centre the  
saw blade in the kerf and check that saw teeth are not  
engaged into the material. If saw blade is binding, it may  
walk up or kickback from the workpiece as the saw is  
restarted.  
g. Always use blades with correct size and shape (diamond  
versus round) of arbour holes. Blades that do not match  
the mounting hardware of the saw will run eccentrically,  
causing loss of control.  
d. Support large panels to minimise the risk of blade  
pinching and kickback. Large panels tend to sag under  
their own weight. Supports must be placed under the  
panel on both sides, near the line of cut and near the  
edge of the panel.  
h. Never use damaged or incorrect blade washers or bolt.  
The blade washers and bolt were specially designed  
for your saw, for optimum performance and safety of  
operation.  
Causes and operator prevention of kickback:  
Kickback is a sudden reaction to a pinched, bound or  
misaligned saw blade, causing an uncontrolled saw to lift  
up and out of the workpiece toward the operator;  
e. Do not use dull or damaged blades. Unsharpened or  
improperly set blades produce narrow kerf causing  
excessive friction, blade binding and kickback.

f. Blade depth and bevel adjusting locking levers must be  
tight and secure before making cut. If blade adjustment  
shifts while cutting, it may cause binding and kickback.  
Contents of carton  
The GMC LS1375 Circular Saw is supplied with the  
following accessories as standard:  
g. Use extra caution when making a “plunge cut” into  
existing walls or other blind areas. The protruding blade  
may cut objects that can cause kickback.  
Blade (fitted)  
Blade key  
Parallel fence  
The protruding blade may cut objects that can  
cause kickback.  
Unpacking  
a. Check lower guard for proper closing before each use.  
Do not operate the saw if lower guard does not move  
freely and close instantly. Never clamp or tie the lower  
guard into the open position. If saw is accidentally  
dropped, lower guard may be bent. Raise the lower guard  
with the retracting handle and make sure it moves freely  
and does not touch the blade or any other part, in all  
angles and depths of cut.  
Due to modern mass production techniques, it is unlikely  
that your GMC Power Tool is faulty or that a part is missing.  
If you find anything wrong, do not operate the tool until the  
parts have been replaced or the fault has been rectified.  
Failure to do so could result in serious personal injury.  
Assembly  
The GMC circular saw is packed, fully assembled except for  
the parallel fence.  
b. Check the operation of the lower guard spring. If the  
guard and the spring are not operating properly, they  
must be serviced before use. Lower guard may operate  
sluggishly due to damaged parts, gummy deposits, or a  
build-up of debris.  
c. Lower guard should be retracted manually only for  
special cuts such as “plunge cuts” and “compound cuts.”  
Raise lower guard by retracting handle and as soon  
as blade enters the material, the lower guard must be  
released. For all other sawing, the lower guard should  
operate automatically.  
d. Always observe that the lower guard is covering the  
blade before placing saw down on bench or floor. An  
unprotected, coasting blade will cause the saw to walk  
backwards, cutting whatever is in its path. Be aware  
of the time it takes for the blade to stop after switch is  
released.
