BLADE RAISING AND TILTING MECHANISM (FIG. LL)

After each fi ve 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 fi nger-tight against the bracket (4), and 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 in. (4 mm).

Place a small amount of dry lubricant on bevel gear (2). Screws 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, 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.
