Personal safety  
General safety instructions  
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.  
WARNING. Read and understand 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 below refers to your  
mains-operated (corded) power tool or battery-operated  
(cordless) power tool.  
Use safety equipment. Always wear eye protection.  
Safety equipment such as a dust mask, non-skid  
safety shoes, hard hat, or hearing protection used for  
appropriate conditions will reduce personal injuries.  
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.  
Remove any adjusting key or wrench before  
turning the tool on. A wrench or a key that is left  
attached to a rotating part of the power tool may  
result in personal injury.  
Do not overreach. Keep proper footing and balance at  
all times. This enables better control of the power tool  
in unexpected situations.  
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.  
If devices are provided for the connection of dust  
extraction and collection facilities ensure that these  
are connected and properly used. Use of these devices  
can reduce dust-related hazards.  
Save these instructions  
Work area  
Keep work area clean and well lit. Cluttered and dark  
areas invite accidents.  
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.  
Keep children and bystanders away while operating a  
power tool. Distractions can cause you to lose control.  
Electrical safety  
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.  
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.  
Do not expose power tools to rain or wet conditions.  
Water entering a power tool will increase the risk of  
electric shock.  
Power tool use and care  
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.  
When operating a power tool outdoors, use an  
outdoor extension cord suitable for outdoor use. Use  
of a cord suitable for outdoor use reduces the risk of  
electric shock.  
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 nameplate of the tool. A power source with a voltage  
greater than that specified for the tool can result in  
serious injury to the user, as well as damage to the tool.  
If in doubt, do not plug in the tool. Using a power source  
with a voltage less than the nameplate rating is harmful  
to the motor.  
Always remove the plug from the mains socket before  
making any adjustments or maintenance, including  
changing the blade.  
When operating the saw, use safety equipment including  
safety goggles or shield, ear protection, dust mask and  
protective clothing including safety gloves.  
Do not use this saw to cut firewood.  
Ensure that the lighting is adequate.  
Keep the area free of tripping hazards.  
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.  
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.  
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.  
Maintain power tools. Check for misalignment or  
binding of moving parts, breakage of parts and any  
other condition that may affect the power tool’s  
operation. If damaged, have the power tool repaired  
before use. Many accidents are caused by poorly  
maintained power tools.  
Do not let anyone under the age of 18 years operate  
this saw.  
Always stand to one side when operating the saw.  
Keep cutting tools sharp and clean. Properly  
maintained cutting tools with sharp cutting edges are  
less likely to bind and are easier to control.  
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 intended could result in a  
hazardous situation.  
Never use a cracked or distorted saw blade. Only use  
sharp blades.  
When cutting round wood, use clamps that prevent the  
work piece from turning on both sides of the blade.  
Never use your hands to remove sawdust, chips or waste  
close to the blade.  
Use only blades as recommended.  
Do not use blades of High Speed Steel (HSS blades)  
Do not use a blade unless the rated blade speed exceeds  
the saw no-load speed.  
Service  
Rags, cloths, cord and string and the like should never  
be left around the work area.  
Avoid cutting nails. Inspect the work piece and remove  
all nails and other foreign objects before beginning  
sawing.  
Support the work properly.  
Never reach over the blade to remove waste or off cuts.  
Have your power tool serviced by a qualified repair  
personnel using only identical replacement parts.  
This will ensure that the safety of the power tool  
is maintained.

Do not attempt to free a jammed blade before first  
switching off the machine.  
Do not slow or stop a blade with a piece of wood. Let  
the blade come to rest naturally.  
If you are interrupted when operating the saw, complete  
the process and switch off before looking up.  
Periodically check that all nuts, bolts and other fixings  
are properly tightened.  
The manufacturer shall not be liable for any changes  
made to the tool nor for any damage resulting from such  
changes.  
Even when the tool is used as prescribed it is not possible  
to eliminate all residual risk factors. The following hazards  
may arise in connection with the tool’s construction and  
design:  
Contact with the blade.  
Kickback of work piece and parts of work piece.  
Blade fracture  
Do not store materials or equipment above a machine  
in such a way that they could fall into it.  
Always hold the saw on parts that are insulated. If you  
accidentally cut into hidden wiring or the saw’s own  
cable, the metal parts of the saw will become “live.  
Never saw near combustible liquids or gases.  
Note the direction of rotation of the motor and the  
blade.  
Catapulting of blade pieces.  
Damage to hearing if effective earmuffs are not worn.  
Harmful emissions of sawdust when the machine is  
used in closed rooms. Always use supplementary dust  
extraction where possible.  
Do not use blades that are deformed or cracked.  
Do not lock the movable guard in the open position and  
always ensure that it is working properly, freely rotating  
and returning to fully cover the teeth of the blade.  
Fully unwind cable drum extensions to avoid potential  
overheating.  
When an extension cable is required, you must ensure  
that it has the correct ampere rating for your power tool  
and has a safe electrical condition.  
The base plate must always be held firmly against  
the material being cut to reduce saw vibration, blade  
jumping and blade breakage.  
Do not cut materials containing asbestos.  
Do not use metal or stone cutting blades. Only use  
wood saw blades.  
The tool must be used only for its prescribed purpose.  
Any use other than those mentioned in this Manual will  
be considered a case of misuse. The user and not the  
manufacturer shall be liable for any damage or injury  
resulting from such cases of misuse.

Overview  
Adjusting the depth locking lever  
If the locking lever cannot be tightened enough to lock  
the pivot point, it is time to adjust it.  
1. Ensure the power is  
disconnected from the  
mains socket.  
The saw is capable of ripping and cross cutting  
hardwoods, softwoods and man made boards quickly,  
accurately and safely.  
If the tool becomes too hot, let it run under no load for  
2–3 minutes to cool the motor.  
The quality of the cut will improve as the number of blade  
teeth increases.  
The blade cuts on an upward stroke and may chip the  
uppermost surface or edges of your work piece. When  
cutting, ensure that your uppermost surface is a non-  
visible surface when your work is finished.  
2. With a pair of circlip pliers  
or a flat screwdriver blade,  
carefully remove the circlip  
from the pivot point nut.  
3. Take off the lever and move  
it back one section.  
By slackening the bevel adjustment knob (6), the body  
and the blade of the saw can be tilted to any angle up to  
45° for making angle cuts. Please note that the maximum  
depth of cut is reduced when cutting at an angle.  
4. Replace lever and carefully re-fit the circlip.  
5. Check the pivot point now locks tight when the lever is  
pushed over to tighten.  
Adjusting the bevel angle  
A fixed guard (13) encloses the upper part of the  
blade. As the saw advances through the work piece, the  
retracting blade guard (11) is pushed back by the edge  
of the wood to expose only that part of the blade which  
is needed. When the blade clears the work, the retracting  
blade guard snaps back to completely enclose the blade.  
Caution. Always ensure that the saw is switched off and  
unplugged from the power supply before making any  
adjustments.  
1. Loosen the bevel  
adjustment knob (6).  
Adjusting the cutting depth  
Caution. Always ensure that the saw is switched off and  
unplugged from the power supply before making any

5. Make sure guarding is suitable so that the operator  
cannot touch the saw blade when the blade is  
spinning.  
6. Make sure an anti-kickback device is fitted to your saw  
bench.  
7. Make sure a suitable safety off switch is fitted to the  
saw bench. The saw switch may then be locked on  
using a spring clamp, cable tie or similar and then  
plugged into the safety socket on the saw bench. This  
clamp MUST be taken off when the saw is removed  
from the saw bench.
