Maintenance Guide; Planer Blade Height Adjustment - Hitachi P 20DA Technical Data And Service Manual

7. MAINTENANCE GUIDE

As suggestions for the use and general maintenance of the planer are covered in the Handling Instructions, only
special suggestions relative to planer blade adjustment, disassembly, reassembly and repair are described here.
Thorough attention in handling should be exercised at all times to carefully maintain the flatness and alignment
between the front and rear surfaces of the bases, and to avoid possible injury when installing, adjusting or
handling the planer blades. In addition, ensure without fail that the battery is removed from the main body prior to
carrying out maintenance, cleaning, blade replacement, etc. The [Bold] numbers in the descriptions below and
the circled numbers in the following figures correspond to the item numbers in the Parts List and exploded
assembly diagram.
