5 SERVICE AND MAINTENANCE
MAINTENANCE SAFETY
• Good maintenance is your responsibility. Poor
maintenance is an invitation to trouble.
• Follow good shop practices:
- Keep service area clean and dry.
- Be sure electrical outlets and tools are prop-
erly grounded.
- Use adequate light for the job at hand.
• Turn machine OFF, shut down and lock out pow -
er supply (safety lockout devices are available
through your Harriston dealer parts department)
and wait for all moving parts to stop before ser-
vicing, adjusting, maintaining or repairing.
• Do not work on Clod Hopper electrical system
unless the power cord is unplugged or the pow-
er supply is locked out. Lock-out tag-out pow-
er source before performing any maintenance
work.

as eye, hand and hearing protectors, when per-
forming any service or maintenance.
• Where replacement parts are necessary for pe -
riodic maintenance and servicing, genuine fac-
tory replacement parts must be used to restore
your equipment to original specifications. The
manufacturer will not be responsible for injuries
or damages caused by use of unapproved parts
and/or accessories.

kept readily accessible while performing mainte-
nance on this equipment.

5.1.2 GREASING
Refer to Section 5.1.1 for recommended grease. Use
the Maintenance Checklist provided to keep a record
of all scheduled maintenance.
1. Use only a hand-held grease gun for all greasing.
Air powered greasing systems can damage the
seals on bearings and lead to early bearing failure.
2. Wipe grease fitting with a clean cloth before greas-
ing to avoid injecting dirt and grit.
3. Replace and repair broken fittings immediately.
4. If a fitting will not take grease, remove and clean
thoroughly. Also clean lubricant passageway.
Replace fitting if necessary.
5.
Storing Lubricants:
Your machine can operate at top efficiency only if
clean lubricants are used. Use clean containers to
handle all lubricants. Store them in an area protect-
ed from dust, moisture and other contaminants.
6. Sealed Bearings:
Sealed bearings are used in all locations on the
machine except for the steering swivel castor point
bushings and at the discharge conveyor hinge piv-
ot. Do not grease any sealed bearings on the
Clod Hopper.
