Section 4 Maintenance and Troubleshooting

Maintenance

Regular maintenance will improve perfor-
mance and extend engine/equipment life. The
manufacturer recommends that all mainte-
nance work be performed by an Independent
Authorized Service Dealer (IASD). Regular
maintenance, replacement or repair of the
emissions control devices and systems may
be performed by any repair shop or person of
the owner's choosing. However, to obtain
emissions control warranty service free of
charge, the work must be performed by an
IASD. See the emissions warranty.

Preventive Maintenance

Dirt or debris can cause improper operation

air openings.

debris.

Inspect High-Pressure Hoses

High-pressure hoses can develop leaks from
wear, kinking, or abuse. Inspect hoses before
each use. Inspect for cuts, leaks, abrasions,
bulging, and damage or movement of cou-
plings. If these conditions exist, replace hose
immediately.
NOTE: DO NOT repair high-pressure hose.
Replace with hose that meets or exceeds
maximum pressure rating of unit.
