Operation Instructions - Hotsy 1065SS Operating Instructions And Parts Manual

Before Starting
1. Read all manuals provided with this pressure washer.
Become familiar with location and function of all
operating and safety controls.
WARNING: Check hoses, fittings, wand, trigger gun
and fuel connections daily for signs of wear, cracks
and looseness, and replace as required.
2. Connect water supply hose to the garden hose con-
nector located on pump. The water faucet and supply
hose must be capable of providing a minimum of 3.5
gallons per minute (GPM).
3. Fill oil burner fuel tank. Use kerosene, #1 grade home
heating oil, #1 or #2 diesel fuel. DO NOT USE GASO-
LINE, CRANKCASE OIL DRAININGS, OR WASTE OIL.
WARNING: DO NOT fill engine fuel tank while engine
is running or hot. Let engine cool before refueling or
spontaneous fire may result. Fuel spillage or vapors
could ignite if engine is hot.
4. Fill the engine fuel tank. Do not overfill, fill to the
bottom of filler neck only. Use lead free gasoline
minimum 86 octane. DO NOT use gasoline containing
more than 15% MTBE, 5% methanol or 10% ethanol.
Refer to the provided gasoline engine manual for
additional details.
5. Check pump and engine oil levels.
6. If detergents are to be used, only use detergents
intended for pressure washers. Follow instructions on
the detergent container.
IMPORTANT: Before installing pressure nozzle on
initial start-up, turn on the water supply and allow
water to run from the end of the wand until clear to
prevent the pressure nozzle from clogging.
IMPORTANT: If the pressure washer has not been
used for an extended period of time, remove the
pressure nozzle from the end of the wand and turn
on water supply. Allow water to run from the end of
the wand until clear.
7. Install the proper pressure nozzle for your cleaning

IMPORTANT: The trigger gun provided with this pres-
sure washer is equipped with a manual trigger lock to
prevent accidental operation of the trigger gun. (Refer
to Figure 6.) The manual trigger lock should be used
whenever the trigger gun is not in use.
To Start
IMPORTANT: The water must be turned on before
starting. Running the pump dry will cause damage
and void warranty.
IMPORTANT: DO NOT allow the machine to run with
trigger of the trigger gun released for more than
2 minutes at any one time or damage to pump may
occur.
1. Turn ON water supply.
2. Hold wand firmly, release trigger of trigger gun.
3. Place engine ON/OFF switch in the ON position.
4. Open fuel shutoff valve (if so equipped). Move choke
lever to FULL CHOKE position, (choke may not be
needed on warm engine). Move throttle lever to HALF
THROTTLE position.
5. Pull the rope starter slowly until resistance is felt, then
pull briskly. Do not allow the rope starter to snap back
against the engine. Return it gently to prevent damage
to the starter.
6. When the engine starts, move choke lever until
engine runs smoothly. When engine warms, move
choke lever to NO CHOKE position. Move throttle
lever to FULL THROTTLE position.
IMPORTANT: To allow for proper battery charging,
the throttle control must be kept in the full throttle
position during operation.
NOTE: If engine fails to start, refer to Troubleshooting
Guide in this manual.
7. Squeeze trigger of trigger gun and allow air to purge
from system.
8. If hot water is desired, adjust the thermostat to the
proper temperature and turn burner switch ON. The
burner will light immediately with a small puff of smoke.
You may need to initially adjust your burner for peak
performance. See Oil Burner section under Installa-
tion. When the trigger of the trigger gun is released or
when the thermostat temperature setting is reached,
the burner will automatically turn off.
To Clean
The detergent injector valve operates by reducing the
volume of water, thus a vacuum is achieved and detergent
is drawn into the system. DO NOT reduce the water
inlet flow so the pump cavities due to water starvation.
Operating a pump with insufficient water will damage
the pump seals.
1. Insert detergent inlet line into container of mixed
detergent.
