Lubrication
1. The recommended lubrication for roller
chains used in medium to slow speed
operation is to simply wipe the chain clean.
When there is an appreciable build up of
dust, dirt or wood shavings, use an oil cloth
but never pour the oil directly on the chain.
Over-oiling defeats the purpose of the
lubrication, since it tends to invite the
collecting of dust, shavings, etc. and works
into members of the chain. This hastens
wear and leads to premature replacement.
2. The bearings on the cutterhead are factory
lubricated and sealed. They require no
further attention.
3. When using the planer/molder in a high
humidity area, the four corner screws,
shown in Figure 44, should be coated with
grease or a rust-preventative.
4. The oil in the gearbox should be drained
and replaced about every 2,500 hours of
use. Multi-purpose 70 to 90 weight gearbox
oil is suitable.

Troubleshooting: Mechanical and Electrical Problems
Trouble Probable Cause Remedy
Knife projection incorrect. Adjust height of knives (see page 9).
Uneven depth of cut
side-to-side
Cutterhead not level with bed. Level bed (see page 14).
Table adjustment
difficult
Corner screw too tight. Adjust corner screws.
Board thickness does
not match depth of
cut scale
Depth of cut scale incorrectly set.
Adjust depth of cut scale (see pages
10-11).
Inadequate tension. Adjust chain tension.
Springs on feed rollers compressed
too tightly.
Adjust roller height/spring tension to
allow more movement of spring (see
pages 12-13).
Sprockets are misaligned. Align sprockets.
Chain jumping
Sprockets worn. Replace sprockets.
