Maintenance - Wen 6550 Instruction Manual

CHECK FOR WORN BLADES
Condition of blades will affect the precision of cuts. Observe the quality of the cut that the planer produces to
check the condition of the blades. Dull blades will tear, rather than sever wood fibers and produce fuzzy appear-
ances. Raised grain will occur when dull blades pound on wood that has varying density. Raised edges will also be
produced where the blades have been nicked. Blades on this planer are reversible and should always be reversed
or replaced as a matched set. Keeping a spare set of blades on hand is recommended.
CHANGING BLADES (FIGURES 9, 10, 11)
WARNING: Always turn the planer OFF and disconnect it from
the power source before starting any maintenance work.
Loosen and remove thumb screws from blade guard on the rear
side of planer. Remove blade guard. Carefully turn cutterhead by
hand towards you until it is stopped by the self-engaging latch.
Loosen and remove six bolts from gib. Remove gib using mag-
nets 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.
The blade is held in position by two pins. Gently lift the old
blades from the cutterhead using magnets. Do not make contact
with the blade using fingers. Use magnet only.
Reverse or replace blade and carefully position it on the two pins
using 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. Depress
latch to release cutterhead. Release latch when cutterhead can
be turned by hand. Turn cutterhead by hand until it is stopped by
selfengaging latch.
Remove gib and blade as mentioned earlier. Replace with new
blade. Replace gib and secure it as mentioned earlier. Replace
blade guard and secure it using two bolts.
