Maintenance And Inspection - Hitachi Koki P 20SB Manual De Instrucciones E Instrucciones De Seguridad

(2) Cutter blade sharpening intervals:
Cutter blade sharpening intervals depend on the
type of wood being machined and the cutting
depth. However, sharpening should generally be
effected after each 1,640ft (500m) of cutting
operation.
(3) Grinding allowance of the cutter blades:
As illustrated in Fig. 19, a grinding allowance of
0.14" (3.5mm) is provided for on the cutter blade.
That is, the cutter blade can be repeatedly
sharpened until its total height is reduced to 0.96"
(24.5mm).
(4) Grinding Stone
When a water grinding stone is available, use it
after dipping it sufficiently in water since such a
grinding stone may be worn during grinding
procedures, flatten the upper surface of the
grinding stone as frequently as possible.

MAINTENANCE AND INSPECTION

WARNING:
1. Inspecting the cutter blades:
Continued use of dull or damaged cutter blades will result in reduced cutting efficiency
and may cause overloading of the motor. Sharpen or replace the cutter blades as often
as necessary.
2. Handling:
CAUTION:
● The front base, rear base, and cutting depth control knob are precisely machined to
obtain specifically high precision. If these parts are roughly handled or subjected to
heavy mechanical impact, it may cause deteriorated precision and meduced cutting
performance. These parts must be handled with particular care.
3. Inspecting the screws
Regularly inspect all screws and ensure that they are fully tightened. Should any of the
screws be loosened, retighten them immediately.
WARNING:
Be sure to switch power OFF and disconnect the plug from the
receptacle during maintenance and inspection.
Using this planer with loosened screws is extremely dangerous.
