English
Mounting / dismounting / setting-up of
some elements is the same for all power
tool models, in this case specific models
are not indicated in the illustration �
Installation / dismantling of the side stop (see fig. 1)
• Assembly side stop
12
as it is shown in fig. 1.
• Install the side stop 12 using the wing screw 14 (see
fig. 1).
• Disassembly operations do in reverse sequence�
Setting of grooving width (see fig. 2)
• Loosen the fastening nut
21
of the side stop
12
, and
set the necessary width of grooving by moving the
thrust plate 20 (see fig. 2).
• Tighten the fastening nut 21 �
Installation / dismantling of the vertical stop (see
fig. 3)
• Install the vertical stop 13 using the wing screw 14
(see fig. 3).
• When dismantling the vertical stop 13 unscrew the
wing screw 14 �
Setting of grooving depth (see fig. 3)
• Loosen the wing screw 14 of the vertical stop 13 and
set the desired depth of grooving (see fig. 3).
• Tighten the wing screw 14 �
Initial operation of the power tools
Always use the correct supply voltage the power sup-
ply voltage must match the information quoted on the
power tool identification plate.
Switching the power tool on / off
Switching on:
In order to switch on the power tool, push lock-off button 6
and while holding it in position, push on / off switch 5 �
Switching off:
In order to switch off the power tool, release on / off
switch 5 �
Dust suction during the power tool op -
eration
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 4 to the right or to the left, according to the
marks of scale 3 �
Scale marking 3 is done such that turning of handle 4
for one mark will change the planing depth by 0�5 mm
(see fig. 4). For example, 0.5 has been preset, by turn -
ing the handle we set value 10 it means that the plan-
ing depth will change from 0�5 mm to 1 mm�
Safety stop (see fig. 5)
Spring-loaded safety stop 8 allows putting the power
tool aside right after completion of the operation, with-
out any risk to damage the treated surface or the pow-
er tool blades� When the power tool is lifted above the
treated surface spring actuated safety stop 8 returns
into the initial position, and during putting aside back
base plate 9 does not contact the treated surface (the
power tool is supported by safety stop 8 ), this pro-
vides free rotation of drum not contacting the treated
surface with blades (see fig. 5).
During planing safety stop
8
moves backward and
ensures free operation�
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
maximum speed�
• After that evenly move the power tool forward� Control
the conveying speed - performance of operation will
take some time� Too high speed would not expedite 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
