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.
When not in use, store the equipment somewhere
clean, dry and safe from thieves.
Remove the saw from the cut while still running, then
release the ON/OFF trigger and wait for the blade to
stop.
Then unplug the saw and refit the plastic guard strip
supplied to protect the blades. Take care though - the
blades are very sharp.
All that remains is to give the unit a final clean up ready
for return, to your local HSS Hire Shop.
FINISHING OFF
Blade Replacement
Switch the unit OFF and unplug it from the power
supply. Wearing suitable gloves, turn the unit up-
side-down and where fitted, remove the dust
extraction cover.
Model 1.
Working on one blade at a time, turn the blade
locking hex bolt anticlockwise with the hex key
until the blade and bolt separate. The bolt is spring
loaded and held captive.
Lift the blade by the heel end. Fully raise the
blade until it disconnects from the front guide slot
of the main bar. Repeat with the remaining blade.
The blades can only be replaced one way and left
and right cannot be incorrectly fitted.
To refit, insert the tip of one blade into the main
bar until the tip clicks into the guide slot. Lower
the heel and align its female thread with the
captive hex bolt and turn the bolt clockwise to
secure in place. Repeat with the remaining blade.
Model 2.
Depress the blade lock button and lift the blades
by the heel end. Fully raise the blades until they
disconnect from the front guide slots of the main
bar.
The blades are colour coded red and green. When
replacing, fit the red set first followed by the green.
To refit, depress the blade lock button and insert
the heel of the red blade onto the drive pin then
lower it into the main bar until the tip clicks into
the guide slot.
Repeat with the green blade then release the
blade lock button.

Most HSS Heavy Duty Saws plug into a standard
230V 13amp power socket. However, 110V models
(with a round yellow plug) must be provided with a
suitable 110V 16amp generated supply, or powered from
the mains via a suitable 110V transformer.
If the equipment fails, or if its power supply cable or
plug becomes damaged, return it. Never try to repair
it yourself.
Keep cables out of harm’s way, and clear of the work
area.
Extension leads should be fully unwound and
loosely coiled, away from the equipment. Never run
them through water, over sharp edges or where they could
trip someone.
Keep the equipment dry, using electrical equipment
in very damp or wet conditions can be dangerous.
To reduce the risk of electric shock, always use a
suitable RCD (Residual Current-Operated Device)
available from your local HSS Hire Shop. Or power the
equipment from a mains circuit with a built in RCD.
Ensure the machine and power socket are switched
OFF before plugging into the power supply.
Remove the clip on plastic strip used to protect the
blades. You can now plug the saw into its power
supply and switch the supply ON.
Where necessary, secure the workpiece with a vice or
clamps, making sure off cuts have enough support to
stop them breaking off unexpectedly or pinching the blades.
Ensure that the workpiece is free from screws, nails
etc.
Switching ON Model 1...
To switch the saw ON, depress the safety catch with
your thumb, and squeeze the ON/OFF trigger.
Switching ON Model 2...
To switch the saw ON, depress the operators
presence button (OPB) with your thumb, and
squeeze the ON/OFF trigger. The Heavy Duty Saw
saw is fitted with a OPB on either side of the rear handle.
Use the button that is most comfortable for you.
Grip the saw firmly in both hands one on the trigger
grip, the other on the front handle. Never use the saw
using only one hand.
Adopt a comfortable, stable stance that gives a
clear view of what you are doing while keeping the
whole of your body behind the cutting edge.
You can then start work when the blades reach
operating speed.
Let the saw do the work, apply just enough pressure
to ensure reasonable progress.
Always cut in a straight line, never twist the blade in the
cut.
The 230V version of Model 2 Heavy Duty Saw is
fitted with an adjuster to vary the speed of the
blades. The speed adjuster dial is located on the top of
the rear handle.
If you are cutting plastic, which may melt and clog
the blades, reduce the speed with the adjuster dial.
For best results when cutting wood, keep the speed
set to maximum (6),
Avoid prolonged heavy use at low speed settings as
this may lead to overheating of the motor. DO NOT
adjust the speed of the blades with the unit
running. Release the ON/OFF trigger, make the
adjustment and restart the unit.
