Drive Belt Maintenance - North Star 1572081 Owner's Manual

Drive Belt Maintenance

Check drive belt tension after first 24 hours of
running and then routinely with each oil change.
Tighten or replace belts as needed. Always tighten
belts if slipping.
WARNING: Filter Disposal
Belt slippage can cause static electricity
build-up, which may result in sparking. Fire
ignition can result.
Instructions:
1) Make sure engine is off and spark plug wire is
removed.
2) Remove belt guard. See "Parts Breakdown" section
of this manual for location.
3) Loosen pump mounting bolts (4).
4) Inspect belts for wear/damage. Replace as needed.
When replacing belts, always replace all – don't mix
old and new belts.
5) Tighten tension bolt to achieve the recommended
belt tension specified below. (Tightening the
tension bolt pulls the pump away from the engine,
tightening all two belts simultaneously.)

Note: Some general rules of belt tension are:
 The ideal tension is the lowest tension without belt
slippage
 Over tightening decreases belt and bearing life.
 Keep belts clean and free of foreign material that
may cause slippage
 Do not apply belt dressing, which can cause
damage and early belt failure.
6) Ensure all belts are the same tension.
7) Re-tighten pump mounting bolts. Torque to 29.4 ft-
lbs.
8) Replace belt guard.
WARNING: Entanglement
Do not operate unless belt guard is in place
to prevent access to rotating parts. Clothing
or hair can become rapidly entangled in
unguarded rotating parts, resulting in serious
injury or death.
NOTE TO COMMERCIAL USERS:
All mechanical equipment, no matter how well designed,
will need maintenance and repairs. A NorthStar
pressure washer is no exception. At times, a NorthStar
pressure washer may become inoperable because
repairs are required. NorthStar Product Support will
assist in these repairs as needed, but if an inoperable
pressure washer creates a major expense to your
business, then we strongly recommend the following:
Have a staff person become familiar with the

mechanical operation of the pressure washer and
capable of making minor repairs and performing all
preventative maintenance procedures.
Keep a stock of recommended service parts for

maintenance and minor repairs.
IMPORTANT: Replacement Parts
If a part needs replacement, only use parts that
meet the manufacturer's part number
specifications. Replacement parts that do not
meet specifications may result in a safety
hazard or poor operation of the pressure
washer
