Maintenance - Hitachi C 10FR Instruction Manual

MAINTAINING YOUR TABLE SAW
GENERAL MAINTENANCE
WARNING
For your own safety, turn the switch OFF and remove
the switch key. Remove the plug from the power source
outlet before maintaining or lubricating your saw.
1. Clean out all sawdust that has accumulated inside
the saw cabinet and the motor.
2. Polish the saw table with an automotive wax to keep
it clean and to make it easier to slide the workpiece.
3. Clean cutting blades with pitch and gum remover.
4. A worn, cut, or damaged power cord should be
replaced immediately.
WARNING
All electrical or mechanical repairs should be attempted
only by a trained repair technician. Contact Hitachi
Authorized Service Center for service. Use only identical
replacement parts. Any other parts may create a hazard.
5. Use liquid dish washing detergent and water to clean
all plastic parts.
NOTE: Certain cleaning chemicals can damage
plastic parts.
6. Avoid use of cleaning chemicals or solvents,
ammonia and household detergents containing
ammonia.
BLADE RAISING AND TILTING MECHANISM (FIG. HH)
After each five hours of operation, the blade raising
mechanism and tilting mechanism should be checked
for looseness, binding, or other abnormalities. With the
saw dis-connected from the power source, turn the saw
upside down and alternately pull upward and downward
on the motor unit. Observe any movement of the motor
mounting mechanism. Looseness or play in the blade
raising screw (1) should be adjusted as follows:
1. Using a wrench, loosen nut (2).
2. Adjust nut (3) until it is finger-tight against the bracket
(4), then back off the nut (3) 1/6 turn.
3. Tighten nut (2) with the wrench, while holding nut (3)
in place. Maximum allowable play of screw rod (1) is
0.16" (4 mm).

MAINTENANCE

Fig. HH
Place a small amount of dry lubricant on the bevel gear
(2). The screw rod (1) must be kept clean and free of
sawdust, gum, pitch, and other contaminants for smooth
operations.
If excessive looseness is observed in any parts of the
blade raising mechanism or tilting mechanism, contact
Hitachi Authorized Service Center immediately.
LUBRICATION
All motor bearings are permanently lubricated at the
factory and require no additional lubrication.
On all mechanical parts of your table saw where a pivot
or threaded rod are present, lubricate using graphite or
silicone. These dry lubricants will not hold sawdust as
would oil or grease.
