Hire Shops
A powerful 2 stroke petrol cut off
saw capable of cutting to a depth
of 125mm.
Operating & Safety Guide 912
Once the engine has started, squeeze and release
the throttle to release the trigger lock and set the
throttle in the idling position.
Note that, if restarting after a short break, you do not
need to use the choke.
If the engine floods push both the blue choke lever
and the decompression valve fully in. Squeeze the
throttle and press the trigger lock button to hold
the throttle open, then pull the starter handle
repeatedly until the engine fires.
Adjust the angle of the safety guard to suit the work,
to do this, simply grasp the guard firmly and turn to the
required angle.
Adopt a comfortable, balanced stance that allows
a good view of the cut. Never use a cut-off saw
when standing on an unstable platform, or on slippery,
uneven ground.
Grasp the machine firmly with both hands and
squeeze the throttle trigger to bring the wheel up to
speed before starting the cut. Do not release the
trigger again until the saw is clear of the work.
Use the dust suppression kit to control the dust
created during the cut.
The dust suppression kit must only be used
with diamond wheels, NOT with standard
abrasive wheels.
Let the wheel and saw do the work – don’t try to
force it through the material.
Keep the saw and/or work as steady as possible. Keep
the cut straight and do not allow the cutting
wheel to twist in the cut.
Never push the equipment beyond its design
limits. If it will not do what you want with reasonable
ease and speed, assume you have the wrong tool for the
job. Contact your local HSS Hire Shop for advice.
Handle the equipment with care. Avoid dropping it,
knocking it, or otherwise exposing it to damage.
Never expose the equipment to excessive
moisture, dust or dangerous/corrosive chemicals.
Keep the equipment clean. You will find this less of a
chore if you clean up regularly rather than wait until the
end of the hire period.
If working with very dusty materials, stop work
and clean the saw more frequently.
When not in use, store the equipment somewhere
clean, dry and safe from thieves.
EQUIPMENT CARE
BASIC TECHNIQUES
Be sure to use the correct fuel: a 50 to 1 blend of
unleaded petrol and two-stroke oil. Never use any
other type of oil as a substitute for two-stroke oil.
Move the ON/OFF switch into the OFF position.
Wait for the engine to stop and for the cutting
wheel to become stationary.
If the saw is not to be used again, remove the cutting
wheel by simply reversing the fitting procedure (see
Getting Started).
Finally, dust down the saw before returning it.

your local HSS Hire Shop.
Ensure the guard is correctly fitted and secure

COSHH information sheets are available from your local
HSS Hire Shop.

or abrasive wheels. Diamond wheels are
available to hire, with a wear charge for the

Begin by fitting the appropriate 350mm wheel.
Immobilize the rear flange plate by inserting a
locking pin into the hole in the drive belt housing.
Now, unscrew the flange-retaining bolt, remove
the front flange plate and seat the new wheel
onto the rear flange plate.
GETTING STARTED
Fuel Safety
NEVER refuel while the engine is hot or running.
NEVER smoke or allow naked lights into the
area while refuelling.
ALWAYS mop up fuel spillages as quickly as possible.
Change your clothes if you spill fuel on yourself.
ALWAYS store fuel in an approved container, in
a cool, safe place away from the work area.
Never mix petrol/oil in the machine’s fuel tank.
Refit the front flange plate and screw the flange-
retaining bolt back into place, tightening this up
using the spanner provided. DO NOT OVER-TIGHTEN.
Double check that both flange plates are secure,
the wheel is central and spins freely.
To start the motor...
Mix 5 Litre of unleaded petrol with 1 bottle of HSS
2-Stroke oil in a suitable container, and fill the fuel
tank. Each tank-full gives about 30 minutes use. Never
add the oil and petrol to the tank unmixed.
Slide the ON/OFF switch to the ON position and, if
starting from cold, set the choke. Pull the blue choke
lever fully out and push in the decompression
valve. Now, squeeze the throttle and press the
trigger lock button to hold the throttle open.
Pull the starter handle a few times until the motor
‘coughs’, then push in the blue choke lever, push in
the decompression valve and pull the starter
handle once more. The motor should fire.
