Maintenance - Hi-Tech 22-229 Instruction Manual

OILING
The only parts you need to oil on the trim saw
machine is the inside of the aluminum arbor and
the motor shaft (Fig. E). This is required because
the motor shaft and arbor are made of different
materials. Over time, they can seize together,
making it impossible to remove the arbor from
the shaft. Every two months or so, remove the
arbor from the motor shaft by loosening the two
set screws using the included Allen wrench, turn-
ing counter-clockwise. Once loosened, slide the
arbor off the motor shaft. Apply a few drops of
motor oil, way oil, lithium or water pump grease
inside the arbor where it fits onto the shaft. Also
apply a few drops of oil or grease onto the motor
shaft, rubbing to coat the shaft lightly. Make
sure there is no excess oil so that oil doesn't drip
down the motor shaft and get into the motor.
This will cause an instant motor burn-out.
Replace the arbor onto the shaft, using the Allen
wrench to tighten the two set screws.

CLEANING
After each use, drain the water reservoir. Any used
water must not be disposed down a sink, as rock
sediment can harden like cement, closing off
the drain. Dry the machine and saw blade with
paper towels or a cloth. You may also spin dry the
saw blade by running it on the trim saw until it is
completely dry. Notes: Always dry your saw blade
after each use to prevent rusting. Keep out of reach
of children.
FUSE DETAILS
The fuse is installed in the back of the trim saw
machine. It is a 250V, 2AMP slo-blo cartridge fuse.
If you need a replacement, this fuse can be found
at your local hardware store. See Fig. F for how to
change the fuse.
