Power tool maintenance /
preventive measures
Before carrying out any works on the power tool it
must be disconnected from the mains.

too tight to avoid damaging the thread.
It is required to replace the dull blades in
good time. In order to prevent unbalance
and vibration always replace both blades
at the same time. Use blades of the same
type. Never operate the power planer with only one
blade installed.
Be careful when replacing blades of the
power planer to prevent injuries from
blade edges. After replacement of blades
always rotate drum to make sure that it
has free running. Also check tightening of clamp-
ing bolts 21.
Resharpenable blades 25 may be resharpened.
When the blade edges become blunted resharpen-
able blades 25 should be dismantled, resharpened
by means of a special device. Then they should be
aligned and reinstalled on drum 26. Hereinafter re-
ferred to as "blades".
