Switching off:
In order to switch off the power tool, release on / off
switch 6�
Dust suction during the power
tool operation
Dust suction allows reducing dust concen-
tration in the air and prevents its accumula-
tion at the workplace�
When working with the power tool always
use a suction cleaner to suck off the dust form the
treated materials�
Design features
of the power tool
Additional handle with regulator for planing depth
adjustment (see fig. 4)
Set the desired planing depth turning additional
handle 5 to the right or to the left, according to the
marks of scale 4�
Scale marking 4 is done such that turning of handle 5
for one mark will change the planing depth by 0,25 mm
(see fig. 4). For example, 0 has been preset, by turning
the handle we set value 0,25 it means that the planing
depth will change from 0 mm to 0,25 mm� Handle 5 can
be rotated by 2 full turns and planing depth changes
from 0 to 3 mm�
Recommendations
on the power tool operation
Planing
• Make sure that the workpiece is safely fixed.
• Place front base plate 1 on the treated surface such
that the blades do not contact the treated surface�
• Turn the power tool on and let drum reach the maxi-
mum speed�
• After that evenly move the power tool forward� Con-
trol the conveying speed - performance of operation
will take some time� Too high speed would not expe-
dite the process but will entail the power tool overload
and will result in poor quality of the treated surface�
• When starting the planing process press stronger
the front part of the power tool and at the end of work -
the back part, which allows avoiding uneven chipping
both at the beginning and at the end of planing�
• Planing would be easier if you incline the workpiece
such that it could be planed downwards�
• Do not turn off the power tool during the operation,
first you should break contact of the blades with the
workpiece, for example, lift the power tool above the
treated surface�
Recommendations on improvement of the quality
of the treated surface
Quality of the resulted surface depends on planing
depth, conveying speed, direction of planing and con-
dition of the blades�
• Planing depth - with low depth of planing the re-
sulted surface would be smoother but it would require
more runs to remove the layer of required thickness�
For pre-treatment - set higher value of planing
depth as this will reduce time of work�
For final treatment - set lower value of planing
depth as this will ensure smoother surface�
• Conveying speed - with low depth of planing the
resulted surface would be smoother�
• Direction of planing (along / against fibers) - in
case of planing along the wood fibers the surface
would be smoother�
• Blade condition - in case of planing with dull
blades or with blades with jags or chippage the treated
wood surface may have defects (scuffing, longitudinal
stripes, etc�)� Special attention shall be paid to control
of the blades condition as this will ensure safer opera-
tion and higher results of work�
Edge chamfering (see fig. 5)
V-groove 2 allows chamfering at the edges of treated
workpieces�
Incline the power tool at 45° (see fig. 5) and perform
planing� During operation special attention shall be
paid to angle of the power tool inclination and uniform-
ity of conveying�
Before carrying out any works on the power tool it
must be disconnected from the mains.
Do not draw up the fastening elements
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 19.
Resharpenable blades 23 may be resharpened.
When the blade edges become blunted resharpen-
able blades 23 should be dismantled, resharpened
by means of a special device. Then they should be
aligned and reinstalled on drum 24. Hereinafter re-
ferred to as "blades".
• Turn the power tool over and unscrew bolts 19 using
box wrench 15 (see fig. 6).
• Remove cover 20 and blade 23 assembled with ad-
justing plate 21�
• Unscrew screws 22 and remove adjusting plate 21
from blade 23�
• Clean all parts using a soft brush�
• Sharpen blades 23 as described below�
• Before installation of a new blade 23 make align-
ment using blade alignment fixture 14�
• Place blade 23 on blade alignment fixture 14 (see
fig. 8.2). Attention: blade alignment fixture 14 has
factory setting and does not require any additional
adjustment.
