Maintenance & Repair

Instructions:
1) Inspect magnets, shoes, and magnetic coil for wear. Replace as
needed. Note: Magnets should always be replaced in pairs (both sides
of an axle).
a) Replace magnets and shoes if worn or scored.
b) Replace magnets if wearing unevenly or abnormally.
c) Replace magnets if any part of the magnetic coil becomes visible
through the friction material facing of the magnet.
2) Reface the drum armature surface when replacing magnets.
3) Check springs for stretch or deformation and replace as needed.
4) Clean the backing plate, magnet arm, magnets, and brake shoes.
5) Check for other worn or loose parts.
6) Apply a light film of lubricate or similar grease on:
a) the brake anchor pin,
b) the actuating arm busing and pin,
c) the actuating block that is mounted on the actuating arm, and
d) the areas on the backing plate that are in contact with the brake
shoes and magnet lever arm.
WARNING: Do not get grease oil on brake linings or drums.
Grease on these parts will reduce braking performance.
7) Reassemble brake assembly. Make sure all parts are installed on the
same brake assembly that they were removed from.
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:
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.
