OPERATOR’S MANUAL
LANDA SDHW • REV.12/02
10. Do not operate this product when fatigued or under
the influence of alcohol or drugs. Keep operating area
clear of all persons.
WARNING: Risk of injury — High
pressure spray can cause paint
chips or other particles to be-
come airborne and fly at high
speeds.
11. Eye safety devices, safety cloth-
ing and foot protection must be
worn when using this equip-
ment
CAUTION: Risk of injury — spray gun kicks back.
Hold securely with both hands.
12. Grip cleaning wand securely with both hands before
starting the cleaner. Failure to do this could result in
injury from a whipping wand.
13. Machines with spray gun should not be operated with
the spray gun in the off position for extensive peri-
ods of time as this may cause damage to the pump.
14. Be certain all quick coupler fittings are secured be-
fore using pressure washer.
15. Protect discharge hose from vehicle traffic and sharp
objects.
16. Before disconnecting discharge hose from water out-
let, turn burner off and open spray gun to allow wa-
ter to cool below 100° before stopping the machine.
Then open the spray gun to relieve pressure. Failure
to properly cool down or maintain the heating coil
may result in a steam explosion.
17. The best insurance against an accident is precau-
tion and knowledge of the machine.
18. Landa will not be liable for any changes made to our
standard machines, or any components not pur-
chased from Landa.
WARNING: Risk of electrocution
— Keep wand, hose and water
spray away from electric wiring or
fatal electric shock may result.
19. Read engine safety instructions
provided.
20. Never run pump dry or leave
spray gun closed longer than 5
minutes.
21. Use No. 1 or No. 2 Heating Oil (ASTM D306) only.
NEVER use gasoline in your fuel oil tank. Gasoline
is more combustible than fuel oil and could result in
a serious explosion.
NEVER use crankcase or waste
oil in your burner. Fuel unit malfunction could result
from contamination.
WARNING
RISK OF INJURY:
PROTECTIVE
EYEWEAR AND
CLOTHING MUST
BE WORN.
21. Do not confuse gasoline and fuel oil tanks. Keep
proper fuel in proper tank.
22. Protect machine from freezing.
23. Do not allow acids, caustic, or abrasive fluids to pass
through the pump.
24. Inlet supply water must be cold and clean fresh water.
25. Do not overreach or stand on unstable support. Keep
good footing and balance at all times.
PRE-OPERATION CHECK
❑
Pump oil (SAE 30W non-detergent oil)
❑
Cold water supply (10 GPM • 5/8" • 20 PSI)
❑
Hose, wand, nozzle (nozzle size per serial plate)
❑
Water filter (intact, non restrictive)
❑
Engine Oil (15W - 40 CD/SE)
❑
Engine/Burner fuel - diesel
SETUP PROCEDURES
1. Attach a 5/8" water supply hose to inlet connector.
Minimum flow should be 6 GPM.
2. Attach high pressure hose to discharge nipple using
quick coupler. Lock coupler securely into place by
pulling back coupler collar and inserting it onto dis-
charge nipple, then pushing collar forward to lock in
place.
3. Attach variable pressure wand to spray gun using
teflon tape on threads to prevent leakage.
4. Attach swivel connector on discharge hose to spray
gun using teflon tape on threads.
5. Check oil level on sight glass on side of pump. Oil
should be visible half way up sight glass (SAE 30W
non-detergent).
6. Check engine oil.
7. Fill diesel fuel tank.
8. Install proper battery making sure that the red cable
is attached to the positive terminal. Use only a group
24 battery with a 90 amp hour rating.
9. Adding exhaust vent pipe to your oil fired burner is
not recommended because it restricts air flow caus-
ing carbon build-up. This affects the operation, and
increases maintenance on the coil. If a stack must
be used, refrain from using 90° bends. If the pipe
can not go straight up then use only 45° bends and
go the next size pipe. The overall pipe length must
not exceed 6 feet in length.
10. These machines are intended to be protected from
the outside environment.
WARNING
KEEP WATER SPRAY
AWAY FROM
ELECTRICAL WIRING.
