SECTION 6: MAINTENANCE
Always disconnect power
to the machine before
performing maintenance.
Failure to do this may
result in serious person-
al injury.
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
Daily Maintenance:
•
Check/tighten loose mounting bolts.
• Sharpen/replace damaged or worn knives
(
Page 27).
• Check/adjust knife height ( Page 27).
• Check/repair/replace worn or damaged
wires.
• Resolve any other unsafe condition.
Each 40 Hours of Operation:
•
Lubricate elevation leadscrews ( Page 23).
• Lubricate feed roller chain drive (
Page 23).
• Check/replace motor brushes ( Page 23).
• Check/replace drive belt (
Page 28).
• Check/clean feed rollers ( Page 24).
Schedule
Cleaning the Model G0505 is relatively easy.
Vacuum excess wood chips and sawdust, and
wipe off the remaining dust with a dry cloth. If any
resin has built up, use a resin dissolving cleaner
to remove it.
Cleaning
Knife Sharpening
Knife sharpness is one of the most important
factors in getting good results with your planer.
Knives can last a long time if care is taken in
checking the condition of the workpiece before
putting into the machine. The biggest problem for
the knives comes from stock with nails, pebbles,
or other hard embedded objects. These items will
nick or chip the knives, causing permanent dam-
age. Another wear factor is sand, grit, or other
debris on the workpiece surface. At the speed
the cutterhead is rotating, this type of surface
contamination can have a very abrasive affect on
the knives.
You can use machines such as the Model G2790
Universal Grinder (refer to
Page 21) to sharpen
the knives yourself, or you can use a professional
sharpening service that has the equipment to
ensure that the knife cutting geometry is ground
correctly.
Your planer is shipped with knives that have a
grind angle of 40°, which is a setting that should
suit most general planing needs.
Always grind the knives as a set so they are
matched in weight. Unequal material removal can
result in an unbalanced cutterhead that can affect
not only planing quality, but, ultimately, the life of
the cutterhead bearings.
The optimal grinding process is a compromise
between cutting ability (the smaller the angle, the
better the cutting action) and edge life (the larger
the angle, the more the edge is supported, and
thus, the longer it will last).
To avoid downtime, we recommend having an extra
set of knives on hand (Model H5038 Replacement
Knives in the Grizzly catalog or website).
Note: Refer to Adjusting Knives on Page 27 for
detailed instructions on removing the knives.
