expectations. It has been manufactured under stringent
GMC Quality Standards to meet superior performance
criteria.
You will find your new tool easy and safe to operate,
and, with proper care, it will give you many years of
dependable service.
Caution. Carefully read through this entire Instruction
Manual before using your new GMC Power Tool. Take
special care to heed the Cautions and Warnings.
Your GMC power tool has many features that will make
your job faster and easier. Safety, performance, and
dependability have been given top priority in the
development of this tool, making it easy to maintain
and operate.
Environmental protection
Recycle unwanted materials instead of
disposing of them as waste. All tools, hoses
and packaging should be sorted, taken to
the local recycling centre and disposed of
in an environmentally safe way.

Safety instructions
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.
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.
• 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.
Personal safety
• 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.
• 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.
Power tool use and care
• 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.
• 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.
4

• 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.
• 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.
Service
• 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.
Additional safety rules for saws
• Ensure that the lighting is adequate.
• Keep the area free of tripping hazards.
• Do not let anyone under 18 years operate this saw.
• Always stand to one side when operating the saw.
• 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 by the saw blade.
• Use only blades as recommended.
• Rags, cloths, cord, 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.
• Do not attempt to free a jammed blade before first
switching off themachine.
• 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 fixings are properly tightened.
• 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.

the charger from the mains supply and leave it for at
least 15 minutes. After this time you can charge a
second battery pack.
Additional safety rules for the battery pack
• The battery pack for this tool has been shipped in a low
charge condition. You should charge the battery pack
fully before use.
• Ensure the switch is in the off position before inserting
battery pack. Inserting the battery pack into power
tools that have the switch on invites accidents.
• Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
• To ensure the longest battery life and best battery
performance, always charge the battery when the air
temperature is between 18–24°C. Do not charge the
battery pack when the temperature is below 0°C,
or above 40°C. This is important. Failure to observe
this safety rule could cause serious damage to the
battery pack.
6

• When battery pack is not in use keep it away from
other metal objects like paper clips, coins, keys, nails,
screws or other small metal objects that can make a
connection from one terminal to another. Shorting the
battery terminals together may cause burns or a fire.
• Do not incinerate the battery pack even if it is seriously
damaged or can no longer hold a charge. The battery
pack can explode in a fire.
• Never attempt to open the battery pack for any reason.
If the plastic housing of the battery pack breaks open
or cracks, immediately discontinue its use and do not
recharge it.
• Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from the

You have purchased a 18V heavy duty saw capable of
taking the effort out of many sawing tasks in both wood
and metal. It is robust and extremely versatile.
By changing between the three saw blades provided, it is
possible to use the saw on a wide variety of materials and
in many tasks around the home or workshop.
Fitting and removing the battery pack
To remove the battery pack
from the drill firmly press the
battery release buttons (8) at
either side of the battery pack,
and slide the battery backward
out of the tool.
To install the battery pack,
align rails, on the tool with the
tabs on the battery pack and
slide the battery pack on to the saw. Ensure the battery
pack is sitting straight on the foot and correctly entering
the runners. The battery should slide fully on to the saw
until the battery pack “clicks” into position.
Battery charging
The battery pack for this tool has been shipped in a low
charge condition. You should charge the battery pack fully
before use.
Warning. Do not use an extension cord.
1. Connect the adaptor charger (9) lead to the battery
charger (7).
2. Insert the battery charger (7) into the battery pack (6) and
connect the adaptor charger (9) to a suitable power socket.
3. The battery charge time is
approx. 3–5 hours, after
which the battery pack
should be removed. A good
indication for a fully charged
battery is the temperature of
the battery, which becomes
fairly warm as the battery
becomes fully charged.
4. After normal use, 3 hours of charging time is required for
the battery pack to be fully charged. However, 4–5 hours
charging will ensure a longer run time of your tool.
5. Do not charge batteries for “top up”. Batteries should
be placed on charge only when the battery is noticeably
running down or the tool no longer performs a task it
previously performed.
6. Unplug the adaptor charger and charging slide when not
in use and store them in a dry, secure place.
7. Do not charge your battery pack in temperatures below
0°C or above 40°C.
8. Always remove the battery pack and store it in a dry,
secure place when the tool is not in use.
9. Battery charging should only be carried out indoors.
Warning. Never leave a battery on charge once it starts to
warm up.
Do not charge the battery for more than 8 hours, as this
will damage the battery cells.
If two batteries are to be charged in succession, unplug
the adaptor charger and let it cool down for about 15
minutes before using it for the second battery.
Warning. Consult your local waste authority for
information regarding available recycling and/or disposal
options of a damaged or worn out battery pack.
To obtain the best life for the battery
Never allow the tool to come to a complete stand still
before recharging. The battery should be placed on charge
whenever the battery is noticeably running down or the
tool no longer performs a task it previously performed.
Avoid conducting short charges. Make sure that the battery
is fully charged every time by allowing the charger to
complete its full charging cycle.
Avoid allowing lose items like screws or nails etc to be
stored with battery packs as these or similar items can
short battery packs and cause a fire or explosion.
Always unplug the charger when not in use and store in
a dry secure place.

10
Avoid charging or storing your battery in temperatures
below 0ºC and above 40ºC.
Changing a blade
Caution. Always ensure that the saw is switched off
and unplugged from the power supply before installing
or removing a blade. Make sure that the blade protector
is fitted to the blade to protect your hands and fingers
against the sharp teeth.
Removing a blade.
1. Loosen the Allen screw,
by inserting the allen key
provided and turning it anti-
clockwise. This screw clamps
the blade so that the blade can
be lifted off the retaining pin.
2. Remove the blade from the
saw.
Fitting a blade
3. Position the hole in the blade over the retaining pin.
4. Tighten the allen key by inserting the allen key and
turning it clockwise to clamp the blade in position.
5. Remove the blade protector.
Operation
Switching on and off and controlling the speed.
1. The multisaw has a variable speed trigger switch, the
harder it is squeezed the
faster the saw will operate.
2. This gives the operator
better control when
starting a cut and at break
through, and enables the
speed of cutting to be
varied according to the
circumstances.
3. To switch on, rotate or roll the Lock-off switch (2) to
release the trigger switch, then pull the trigger on.
4. To switch off, release the trigger switch.
General cutting and pruning
(230 & 239 mm blades)
1. Hold the saw firmly with
both hands in front and
clearly away from you.
2. Make sure that the blade is
clear of any obstructions.
3. Ensure that the material to
be cut is held firmly. Small
work pieces should be held in a vice or clamped to the
workbench.
4. Mark out the cutting line.
5. To switch on, rotate or roll the Lock-off switch to release
the trigger switch, then pull the trigger on.
6. Wait until the saw has reached maximum speed.
7. Begin sawing using the same forward and backward
movement you would use with a hand saw.
Note. Use only enough pressure to keep the saw cutting.
Do not force the cutting; allow the blade and the saw to
do the work.
Warning. Use of excessive pressure that causes bending or
twisting of the blade may cause the blade to break.
Warning. Make sure that the blade does not touch the
work piece until the blade has reached maximum speed
since this could cause loss of control and serious injury.
Metal cutting
(200 mm blade)
Metals such as sheet steel,
pipe, aluminium, brass and
copper can be cut with your
saw. Be careful not to bend
or twist the blade and do not
force the cutting action.

11
We recommend that you use cutting oil to lubricate the cut
when sawing soft metals and steel. It keeps the blade
cooler and prolongs blade life.
Caution. Clamp the work firmly and cut close to the
clamping point to minimise vibration. When cutting
conduit pipe or angle iron, clamp the work in a vice if
possible and cut close to the vice. To cut thin sheet metal,
sandwich the sheet between hardboard or plywood and
clamp the layers to prevent vibration and the tearing of
the metal.
Maintenance
Cleaning
1. Keep the tool’s air vents unclogged and clean at
all times.
2. Remove dust and dirt regularly. Cleaning is best done
with compressed air or a rag.
3. Re-lubricate all moving parts at regular intervals.
4. Never use caustic agents to clean plastic parts.
Caution. Do not use cleaning agents to clean the plastic
parts of the saw. A mild detergent on a damp cloth is
recommended. Water must never come into contact with
the saw.
General inspection
Regularly check that all the fixing screws are tight. They
may vibrate loose over time.

Carefully read the entire Instruction Manual
