Operating & Safety Guide 444

Anchor the delivery end of the air hose 

so that it is

not aimed at any person or property then, taking great
care,

slightly open the air supply valve to clear the

hose of any debris. Then fully close the valve.
NOW TURN THE COMPRESSOR OFF, by moving
the ignition key to the ‘0’ position.
You can now connect the hose/s 

between the com-

pressor and whatever it is supplying.

Confirm that the tools air valve is in the closed
position then connect the delivery hose to the tool

in the same way as to the compressor.
All that now remains is to 

check that the air supply

valve is closed and to start the compressor.

This model of compres-
sor is fitted with a ther-
mostatic temperature
gauge which shuts
down the compressor
unit if the air discharge
temperature reaches
110ºC. If during the
course of your work the
air supply stops but the
engine continous run-
ning, check the tempera-
ture gauge.
If the compressor has
overheated, stop the
engine and allow the
compressor to cool
before restarting and
continuing your work.
Make sure you read and
fully understand the

operating instructions supplied with the tool you
are using, if in doubt, contact your local HSS Hire
Shop for advice.

Even if you are only stopping work for a short
break, shut down the compressor completely.
Never push the equipment beyond its design lim-
its. 

If it will not do what you want with reasonable ease,

assume you have the wrong equipment for the job. Ask

at your local HSS Hire Shop
for advice.

Regularly check the fuel
level and top up as neces-
sary 

with unleaded petrol.

Regularly check the oil
level –

when the engine is

cold and on level ground.
Withdraw the dipstick, wipe
it clean, then replace it,
remove it a second time and
verify that the oil level is

EQUIPMENT CARE

between the min and max
lines, 

top up as necessary.

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.

Switch OFF the compressor by turning the ignition
key to the ‘0’ position, close all air taps 

and operate

the equipment fed by the compressor to 

release the

pressure in the hoses. 
If you have finished with the equipment complete-
ly, 

you should now 

clean up the compressor 

as thor-

oughly as possible, 

disconnect the air hoses and

tools then coil them 

neatly ready for return to your

local HSS Hire Shop.
