SECTION 5: MAINTENANCE
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
Daily Check:
• loose mounting bolts.
• damaged or worn grinding wheel.
• loose lock knobs and bolts.
• Worn or damaged wires or switch.
• any other unsafe condition.

Schedule

Cleaning the model t23108 is relatively easy.
disconnect the machine from power and wipe
down the surfaces with a damp shop rag, then dry
them with a clean, dry cloth.

Cleaning

Lubrication

there are not any parts on this sharpener that
require lubrication by the end user.
the bearings of the sharpener motor were lubri-
cated and permanently sealed at the factory and
do not need any further attention unless they
need replacement.

Dressing Wheels

the edge profile and surface condition of the
grinding wheel (see figure 36) is critical in main-
taining the proper shape of the top plate, si de
plate, and gullet when sharpening.
Grinding Wheel Edge Profile
Correct Worn
figure 36. grinding wheel edge profile.
With use, the abrasive surface of the grinding
wheel becomes embedded with material from the
chain, which reduces its effectiveness. in addi-
tion, the side and bottom edge deform and fails
to effectively sharpen the cutter edges. When this
happens, the sharpened surfaces become burned
or discolored, instead of having a clean, silver fin-
ish. additio nally, the angles will not be properly
sharpened.
use the included wheel dressing block to expose
a new abrasive surface on the wheel and to re-
form the side and edge profiles.
Always disconnect power
to the m achine b efore
performing maintenance.
failure to do this may
result in serious person-
