4. Inspecting the blade guard for proper operation
Before each use of the tool, test the blade guard (see Fig. 8) to assure that they are in good condition
and that they move smoothly.
Never use the tool unless the blade guard operate properly and unless they are in good mechanical
condition.
5. Storage
After operation of the tool has been completed, check that the following has been performed:
(1) Trigger switch is in OFF position,
(2) Power plug has been removed from the receptacle,
(3) Stored in a secure place.
When the tool is not in use, keep it stored in a dry place out of the reach of children.
6. Replacement of Poly-V-Belt
The power of the motor is transmitted to the saw blade by a Poly-
V-Belt. When the Poly-V-Belt is broken or damaged, remove the
rear cover by loosening the three 5mm screws and replace the
damaged one with the new one.
When connecting the belt on pulleys, first connect 2 or 3 teeth of
Poly-V-Belt to the grooves of the pulley (A) and pulley (B). Then
turning the pulley (A) and pulley (B), connect all 10 teeth of the belt
to the pulleys.
7. Lubrication
Lubricate the following sliding surfaces once a month to keep the power tool in good operating condition
for a long time (see Fig. 1 and Fig. 2). Use of machine oil is recommended.
Oil supply points:
*Rotary portion of angle regulator
*Rotary portion of vise assembly
*Rotary portion of table and base
8. Cleaning
Periodically remove chips, dust and other waste material from the surface of the power tool, especially
from the inside of the blade guard (plastic) with a damp, soapy cloth. To avoid a malfunction of the
motor, protect it from contact with oil or water.
SERVICE AND REPAIRS
All quality power tools will eventually require servicing or replacement of parts because of wear from
normal use. To assure that only authorized replacement parts will be used and that the double insulation
system will be protected, all service (other than routine maintenance) must be performed by an
AUTHORIZED HITACHI POWER TOOL REPAIR CENTER ONLY.
NOTE: Specifications are subject to change without any obligation on the part of HITACHI.
