MAINTENANCE
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 the following cleaning chemicals or
solvents, ammonia and household detergents
containing ammonia.
BLADE RAISING AND TILTING MECHANISM (Fig. EE)
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).

Place a small amount of dry lubricant on bevel gear (2).
Screw rod (1) must be kept clean and free of sawdust,
gum, pitch, and other contaminants for smooth operation.
If excessive looseness is observed in any parts of the
blade raising mechanism or tilting mechanism, take the
complete unit to Hitachi Authorized Service Center.
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.
