Operations

Operation Instructions

STEP 1:

 

Read operator’s manual 

before operating. Pull wand coupler 
collar back, insert desired pressure 
nozzle into coupler, then secure by 
pushing collar forward. 

CAUTION: Never replace nozzles 
without engaging the safety 
latch on the spray gun trigger.

ATTENTION

Ne jamais 

remplacer les buses sans 
d'abord mettre le dispositif de 
sécurité sur la détente du 
pistolet pulvérisateur.

STEP 4:

 With the spray nozzle 

pointed away from you or anybody 
else, press the trigger on the spray 
gun to obtain pressurized cold 
water spray.

STEP 2:

 Turn on water at faucet 

and pull trigger on spray gun 
allowing water to flow until all air 
has discharged from system. 
Check for water leaks; tighten as 
needed. 

NOTE: 

Variable pressure 

control wand handle must be 
turned clockwise to enable water to 
flow out of the high pressure 
nozzle.

STEP 5:

 For hot water, turn the 

burner switch to ON when a steady 
stream of water flows out of the 
spray gun. Burner will now light 
automatically. 

NOTE:

 Do not start 

machine with burner switch on.

STEP 3:

 Read engine manual. Move 

fuel valve to closed or OFF position, 
if equipped. To start engine, if choke 
is closed, gradually move it to the 
open position as the engine warms 
up. Turn the engine switch to the 
START position and hold it there until 
the engine starts.

NOTE:

 Do not use the electric starter 

for more than five seconds at a time. 
If the engine fails to start, release the 
switch and wait ten seconds before 
operating the starter again. When the 
engine starts, allow the engine switch 
to return to the ON position. If the 
engine is to be started without the 
battery, turn switch to start position 
and pull rope to start. Turn off choke.

WARNING: Small engines may 
kick back. Do not hold pull rope 
tightly in hand. Starter cord 
kickback (rapid retraction) can 
result in bodily injury. 

AVERTISSEMENT: Les petits 
moteurs peuvent présenter un 
risque de retour. Ne pas tenir 
fermement le lanceur moteur. Le 
retour du cordon de lancement 
(rétraction rapide) peut causer des 
lésions corporelles.

NOTE: Kick back will pull hand 
and arm toward engine faster then 
you can let go. Always relieve 
spray gun pressure before pulling 
starter cord. 
Pull starter cord slowly until resis-
tance is felt, then pull rapidly.
