BASIC TECHNIQUES

Trolley Tip

If you wish to use the trolley-mounted version as
a normal cut-off saw, stop the engine and simply
de-mount it from the trolley. It is held in place
with two clamps; one for the saw’s main handle,
the other for the bottom of its front bar grip.
Merely slacken off the clamps’ bolts and lift the
cut-off saw clear. But take care when re­mounting. Make absolutely sure the cut-off saw

is clamped firmly to the
trolley (without over­tightening the clamp
bolts). And check that the
saw’s trigger is operated
by the linkage from the
trolley’s throttle control
and give the unit a final
clean up ready for return,
to your local HSS Hire
Shop.

Adjust the angle of the safety guard to suit the
work using the adjustment knob on the top.

Take special care if the cut-off saw is trolley
mounted. The guard should be set to remain just
clear of the ground (i.e. the surface you are cutting

into) at all times.

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.

Hold 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.
On the trolley-mounted version, the throttle

control is located on the trolley handle and you
simply tilt the trolley backwards or forwards to raise or
lower the wheel as required.

When using the trolley-mounted version, always make

the cut by moving the trolley forwards.

Use the dust suppression kit to control the dust created
during the cut. NOTE: THE DUST SUPPRESSION KIT

MUST ONLY BE USED WITH DIAMOND WHEELS,
NOT WITH STANDARD ABRASIVE WHEELS

Let the Cut Off Saw do the work – don’t try to force

it through the material.
Keep the machine and/or work as steady as possible.

Keep the cut straight and do not allow the cutting
wheel to twist in the cut.

EQUIPMENT CARE

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.

Keep the equipment clean - you will find this less of a
chore if you clean it regularly, rather than wait until the
end of the hire period.

If working with very dusty materials, or if using the
trolley-mounted version, stop work and clean the saw

more frequently.
When not in use, store the equipment somewhere

clean, dry and safe from thieves.

FINISHING OFF

Set the ON/OFF switch into the OFF position. Wait for
the engine to stop and for the cutting wheel to stop
rotating.

If the machine is not to be used again, remove the
cutting wheel by simply reversing the fitting procedure
(see Getting Started).

All that remains is to give the unit a final clean before
returning it to your local HSS Hire Shop.

Once the engine has warmed up release the trigger
lock (squeeze and release the throttle) to set the throttle in

the idling position.

If restarting after a short break, you need only set the
throttle trigger half-open using the throttle lock button. If

the engine floods, push the choke fully in to its off position,
hold the throttle trigger full on, then pull the starter cord
repeatedly until the engine starts.

Now stop the engine

and prepare the work area.

If using the water feed system, connect the unit’s
water connector to a fresh water supply or pressurised

water container.

Never smoke or allow naked lights into the area

while refuelling.

Never inhale fuel vapour.

ALWAYS mop up spillage’s as quickly as possible, and

change your clothes if you get fuel on yourself.

If it shows signs of damage or excessive wear, return it to
your local HSS Hire Shop.

Ensure the guard is correctly fitted and secure

before starting work.
COSHH information sheets are available from your local

HSS Hire Shop.

GETTING STARTED

A range of diamond blades is available on sale or return

to suit most applications. Contact your local HSS Hire Shop.
To fit the 300mm abrasive or diamond wheel, immobilize

the rear flange plate by inserting a locking pin into the
hole in the drive belt housing.

Unscrew the flange retaining bolt with the spanner
provided, remove the outer flange and seat the new

wheel onto the inner flange.
Refit the outer flange and screw the flange retaining

bolt back into place, DO NOT OVERTIGHTEN.
Double check that both flanges are secure, the wheel is

central and spins freely.
Finally, ensure that the safety guard is in the normal

operating position.
Mix 5 Litres 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.

Set the red ON/OFF control to the ON position by
pushing fully in, to switch OFF pull the switch back out again.

If starting from cold, set the blue choke control to ON by
pulling out, then push in the de-compressor button.

The unit is fitted with an operators presence lever

(OPL), the throttle cannot be operated unless the OPL is
firstly depressed.

Now, depress the OPL and operate the throttle trigger,

set the throttle half on and hold using the trigger lock
button.

Set the machine on a firm level surface with the
blade clear of the ground and clear of any obstruction,

as it will rotate as soon as the engine starts.

Pull the starter cord a few times until the engine
'coughs', then push the choke in to it's off position and
pull the starter once more. The engine should start.
