MAINTENANCE
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes, resulting in possible
serious injury.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which could result in serious personal
injury.
Electric tools used on fiberglass material, wallboard, spackling
compounds, or plaster are subject to accelerated wear and
possible premature failure because the fiberglass chips and
grindings are highly abrasive to bearings, brushes, commuta-
tors, etc. Consequently, we do not recommended using this
tool for extended work on these types of materials. However,
if you do work with any of these materials, it is extremely
important to clean the tool using compressed air.
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrica-
tion is required.
POWER SUPPLY CORD REPLACEMENT
If replacement of the power supply cord is necessary, this
must be done by an authorized service center in order to
avoid a safety hazard.
REPLACING THE BLADE
See Figures 22 - 24, page 20.
After extended use, the blade on your biscuit joiner may
become dull and need replacing. If you accidentally hit a nail
or other blunt object, it will break the carbide tips, which will
require replacing the blade.

Unplug the biscuit joiner.
 Remove the dust bag.
 Place the biscuit joiner upside down on a workbench.
 With a screwdriver, remove the four screws and washers
that connect the shoe to the front and rear assemblies.
Remove the shoe.
 Place a screwdriver in the hole provided in the bearing
plate.
 Place one of the non-cutting teeth located behind each
carbide-tipped cutting tooth against the screwdriver or
pin and lock the blade to prevent it from rotating.
DO NOT
lock the blade against one of the cutting teeth. Carbide
tips will break.
 Using a 3/16 in. hex key, remove the blade screw.
NOTE: Turn the blade screw counterclockwise to remove
the screw.
 Remove the outer blade washer, blade and inner blade
washer.
 Clean wood particles and resin from the blade washers,
dust bag area, base assembly, and all surrounding parts.
 Place the inner blade washer on the gear spindle.
 Place the new blade onto the shoulder of the blade washer
and secure with the outer blade washer and the blade
screw.
NOTE: The blade screw fits into the cupped side of the
outer blade washer.
NOTE: The blade teeth point toward the right of the tool
when held in normal operating position. The direction of
rotation is marked on the joiner blade. An arrow on the
bottom of the front base assembly also indicates direction
of rotation.
 Place a screwdriver or pin in one of the two holes provided
in the bearing plate and lock the blade to prevent it from
rotating.
 Turn the blade screw clockwise and tighten securely with
the hex key.
 Replace the shoe.
 Replace the washers and screws and tighten securely
with a screwdriver.
 Replace the dust bag.
