MAINTENANCE (CONTINUED)
•
Using a clean, dry cloth, clean all of the chains and gears of
wood chips, dust, and old grease.
LUBRICATION
•
The table surface can be coated with a lubricant, such as paste
wax, to make the workpiece feed smoother. Be sure that the
lubricant used does not affect the ability to finish the work-
piece with varnish, sealer, etc.
For example, do not use any silicone base lubricants because
they will ruin any attempt to finish the wood.
•
Use common automotive bearing grease to lubricate all chains
and gears. Be sure all chains and gears have plenty of grease.
•
Motor and cutterhead bearings are sealed and need no lubrication.
CHECK FOR WORN BLADES
•
Condition of blades affects precision of cut. Observe quality of
cut which planer produces to check condition of blades.
•
Dull blades tear, rather than sever wood fibers and produce
fuzzy appearance.
•
Raised grain occurs when dull blades pound on wood that has
varying density. Raised edge will also be produced where
blades have been nicked.
REPLACE BLADES
Refer to Figures 14 - 16.
WARNING:
Always turn planer OFF and disconnect from power
source before starting any maintenance work.
NOTE: Always reverse or replace both blades as a set.
•
Remove return rollers.
•
Loosen and remove socket head bolts from blade guard on the
rear side of planer. Remove blade guard.
•
Carefully turn cutterhead by hand towards you until bolts are
accessible.
•
Loosen and remove six bolts from gib.
•
Remove gib using magnets provided.
NOTE: Magnets can be easily disengaged from gib by tilting them
to left or right.
CAUTION:
Blade edges are extremely sharp. Keep fingers away
from blades at all times.
•
Blade is located in position by two pins. Carefully lift old blades
from the cutterhead using the two magnets. Do not make con-
tact with the blade using fingers. Use magnets only.
NOTE: Magnets can be easily disengaged from blade by tilting
them to left or right.
•
Reverse or replace blade and carefully position it on the two
pins using the magnets.
•
Replace gib and align the holes on the gib with holes on the
blade using magnets.
•
Secure gib to cutterhead using six bolts removed earlier.
•
Carefully turn cutterhead by hand until the other blade is accessi-
ble.
•
Remove gib and blade as mentioned earlier.
•
Replace with new blade and replace gib and secure it as men-
tioned earlier.
•
Replace blade guard and secure it using two bolts.
ADJUSTING ROLLERCASE LEVEL
Refer to Figure 17, page 9.
The planer will produce an uneven depth of cut (tapered cut) if
rollercase is not parallel with base. To restore parallelism of roller-
case with base:
•
Using a test piece, measure height of the taper. Determine
which corner or side needs adjustment.
•
Turn planer off and disconnect from power source.
