HSS Hire 07125 Operating & Safety Manual

Mix 5 Litres of unleaded petrol with 1 bottle of HSS
2-Stroke oil in a suitable container, and fill the fuel
tank. Each tankful gives about 30 minutes use. Never
add the oil and petrol to the tank unmixed.
To fit the appropriate disc...
Immobilize the rear flange plate by inserting a
locking pin into the hole in the drive belt housing.
Unscrew the lock nut, remove the outer flange
and seat the new disc onto the inner flange plate.
Refit the outer flange and screw the lock nut back
into place, tightening this up with the box spanner
provided. DO NOT OVERTIGHTEN.
Double check that both flanges are secure, the disc
is central and spins freely.
Finally, ensure that the safety guard is adjusted to a
safe operating position, giving protection to the user.
To start....
Turn the ON/OFF control to the ON position and, if
starting from cold, fully close the choke and where
applicable, push in the decompressor. Now, set the
throttle half on and hold using the trigger lock
button Pull the starter cord a few times until the
engine 'coughs', then fully open the choke and pull
the starter once more. The engine should fire.
Once the engine has warmed up, release the trigger
lock to set the throttle in the idling position and
switch OFF .
Note that if restarting after a short break, you
need only set the choke half open. If the engine
floods, fully open the choke, hold the throttle full on,
then pull the starter cord repeatedly until the engine fires.
Mark the rail at the position to be cut then
dependent on model either...
... fit the cutting gauge onto the rail (see diagram),
align the pointer with the inner edge of the cut
point and secure with the thumbscrew.
Place the support arm on the rail and butt it up to
the gauge, then secure in position (hand tight only).
Now remove the gauge and place somewhere safe, or...
... place the support arm on the rail, swing out the
cutting gauge and align its end with the inner
edge of the cut point. Secure in position (hand tight
only) and swing the guage away from the cut.
Attach the cutter to the support arm, insert the shaft
into the support bracket of the cutter and tighten (again,
hand tight only).
The machine is now ready to be started.
BASIC TECHNIQUES
Once warmed up and with the disc clear of the rail,
squeeze the throttle until full engine speed is
obtained, then bring the disc in contact with the
rail and begin cutting.
Keeping a firm hold of the control handle, allow the
cutter to work at its own pace, DO NOT force
the cut.
Keep the cutter moving over the surface, avoid
cutting at one point as this will cause local heating
(bluing) of the rail end.
If the cutter will not reach the full depth of cut
required, finish the cut from the other side.
Turn the machine OFF , remove it from the support arm
and re-fit from the other side. You may now continue to
finish the cut.
Be careful, any unsupported off-cut may fall and
cause injury to your feet!
EQUIPMENT CARE
Never push the equipment beyond its design
limits. If it will not do what you want with reasonable
ease, assume you have the wrong tool for the job. Ask at
your local HSS Hire Shop for advice.
Always switch OFF the cutter before making any
adjustments to it.
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.
When not in use, store the equipment somewhere
clean, dry and safe from thieves.
Regularly check the fuel level and top up as
necessary, be sure to use the correct fuel: a 50-1
blend of unleaded petrol and 2 stroke oil.
Never use any other type of oil as a substitute for
2 stroke oil.
FINISHING OFF
Switch the ON/OFF switch into the OFF position.
Wait for the engine to die and for the cutting disc
to stop rotating.
If the tool is not to be used again, remove and
dispose of the cutting disc.
Finally, remember to dust down the machine
before returning it to your local HSS Hire Shop.
