PREPARING THE MACHINE FOR USE:
BEFORE TOWING - DAILY
a) Check condition of tyres for sufficient tread depth, cuts, bulges and check inflation
pressure which should be 36 Psi (2.5 bar).
b) Check wheel nuts for tightness. 50 lbf feet (68N ).
c) Check tow coupling for security and ensure that coupling is lightly greased and that it
is adjusted to suit the height of the towing vehicle. Ensure that the adjusting levers
are tight and secured by their locking pins.
d) Check condition of the safety cable.
e) Ensure that all lights are functioning correctly and that reflectors are clean.
Attach a nu ber plate co patible with towing vehicle.

BEFORE STARTING WORK
a) Check engine, gearbox and pu p oil level and top up if required.
b) Fill fuel tank with clean diesel fuel.
c) Ensure unit is standing on level ground.
d) Connect a ains water supply hose to the inlet valve. Fill with clean water only and
ensure that there is sufficient water in the tanks before starting the engine. Confir
that the water supply has sufficient capacity to keep the COMMANDO 5050 supplied
continuously (35 litres/ in).
e) Ensure that high-pressure hose is fitted with either a spray gun or a foot control
pedal and that these are in the OFF position. Where a drain jet only is fitted ensure
that the 3-way valve is in the DUMP position.

e) Open the high-pressure bleed valve and adjust the throttle lever to the ini u
speed position.
f) Depress the protection override button and turn the starter key fully clockwise to start
the engine. In cold weather pause the key at the pre-heat position before cranking the
engine.
g) Once the engine has fired release the key switch and the override button when it is
running s oothly. Adjust the throttle to approxi ately
1
/
3
rd
of full speed. Close the
bleed valve once air free water is issuing. Then turn the 3-way valve to the
PRESSURE position and open the spray gun or foot pedal to expel any re aining air
fro the hose and lance.
NOTE: before turning the valve to the PRESSURE position ensure that the hose reel
lock is ON to prevent it rotating when pressure is applied.
g) When air free water is issuing fro the hose, the unit is ready to use.
h) Increase the engine speed to the desired working level using the throttle. Use of the
throttle will directly affect output water volu e and consequently the pressure.
DURING WORK:
a) Do not leave the COMMANDO
®
5050 idling for periods in excess of 15 minutes, as
re-circulating water heats up rapidly and will eventually boil causing severe
damage to the pump.
b) Should any vibration, fluctuation of pressure or any other abnor al sy pto s occur
during operation it should be investigated i ediately.
Likely causes include:
i) A lack of water entering the unit causing air to be drawn into the pu p.
ii) A blockage of the ain inlet filter causing water starvation at the pu p.
iii) The inlet water valve between tanks and pu p not fully open.
iv) Leaking seals or da aged valves etc.
AFTER WORK
a) To stop the COMMANDO
®
5050 decrease engine revs to idle speed and turn the
starter key to the OFF position.

FROST PROTECTION

HUGH CRANE (Cleaning Equip ent) Ltd – COMMANDO
®
5050 Page 12
It is essential to protect the unit from damage by frost. The following instructions will be
adequate to protect the unit to te peratures down to - 5°C. During winter onths it is
strongly reco ended to store the unit inside whenever possible.
1) Drain ain tanks using drain valve.
2) Run engine for one minute with open ended hoses or gun open to expel all water.
Stop engine.
3) Re ove cap fro inlet strainer and store safely together with its filter screen.
4) During severe weather, the unit should be stored inside, if possible. Where this is
not possible a 25% anti-freeze/water ixture should be introduced into the pu p,
reel, hoses and gun as described below. The antifreeze ixture can be reclai ed
after use for recycling when next required.
5) Close the tank outlet valve, attach the anti-freeze pickup hose and open the
antifreeze valve. Place the hose into the container of anti-freeze and start the
pu p, direct the lance into the container and open the gun. As soon as antifreeze
issues fro the lance, indicating that the hose is filled, close the gun and stop the
engine.
6) The syste is now charged with the anti-freeze solution.
7) Before starting work again the antifreeze ust be e ptied out of the syste by
running the pu p and directing the using the solution back into the container.
8) Always ensure that all anti-freeze solutions are flushed out of the syste before
using the achine for cleaning tasks, as anti-freeze solution can be highly
detri ental to certain surfaces and aterials.
