ADjUSTMENTS
Depth of Cut
The cutting depth scale (Figure 31) is a combination
inch/metric scale, with a cutting range from 0 to 6" (152.4mm).
The distance of upward or downward movement is controlled
by the handwheel. Before moving the table up or down, loosen
the locking handles (Figure 31). After obtaining proper table
position, tighten the locking handles.
Maximum depth of cut is 3/16". A limiter on the front of the
head casting limits the depth of cut on full width planing under
1/8".

MAINTENANCE

Before doing maintenance on the machine,
WARNING
disconnect it from the electrical supply by
pulling out the plug or switching off the main
switch! Failure to comply may cause serious
injury.
Periodic inspections are required to ensure that the machine
is in proper adjustment, that all screws are tight, that belts
are in good condition and properly tensioned, that dust has
not accumulated in the electrical enclosures, and that there
are no worn or loose electrical connections.
Buildup of sawdust and other debris can cause your machine
to plane inaccurately. Periodic cleaning is not only
recommended but mandatory for accurate operation.
Close-fitting parts, such as the cutterhead slots and gibs,
should be cleaned with a cloth or brush and non-flammable
solvent, and freed from clinging foreign matter.
Remove resin and other accumulations from feed rollers and
table with a soft rag and nonflammable solvent.
Periodically check all the chains for proper tension and adjust
accordingly if needed.
The table should be kept clean and free of rust. Some users
prefer a paste wax on exposed steel and cast iron surfaces.
The wax provides a layer of protection as well as reducing
friction between lumber and the table, making cuts faster and
smoother. Avoid any wax that contains silicone or other
synthetic ingredients. These materials can find their way into
lumber and can make staining and finishing difficult.
Another option is talcum powder applied with a blackboard
eraser rubbed in vigorously once a week; this will fill casting
pores and form a moisture barrier. This method provides a
table top that is slick and allows rust rings to be easily wiped
from the surface. Important also is the fact that talcum
powder will not stain wood or mar finishes as wax pickup does.

Lubrication
All ball bearings are factory lubricated and sealed for life.
They require no further lubrication.
The lubricant in the gear box must be drained and replaced
every 2,500 hours. Multi-purpose gear box lubricant will be
suitable.
To replace the lubricant:
1. Remove the drain plug (A, Figure 32) with a 14mm wrench.
Drain dirty oil thoroughly.
2. Insert and tighten the drain plug. (A, Figure 32).
3. Remove filler cap (B, Figure 32) and fill with clean lubricant
through the hole. Fill until the oil reaches the top of the filler
plug port for correct oil level.
4. Install and tighten filler cap (B, Figure 32).
