power tool is supported by safety stop 15), this pro-
vides free rotation of drum not contacting the treated
surface with blades (see fig. 10.2).
During planing safety stop 15 moves backward and
ensures free operation�
Additional handle with regulator for planing depth
adjustment (see fig. 11-12)
Set the desired planing depth turning additional
handle 11 to the right or to the left, according to the
marks of scale 12 (see fig. 11).
Scale marking 12 is done such that turning of handle 11
for one mark will change the planing depth by 0,5 mm
(see fig. 12). For example, 0.5 has been preset, by
turning the handle we set value 1�0 it means that the
planing depth will change from 0,5 mm to 1 mm�
Recommendations on the power tool op-
eration
Planing
• Make sure that the workpiece is safely fixed.
• Select the direction in which the chips are thrown,
install a dust bag 19 or connect the power tool to a
vacuum cleaner�
• Place front base plate 13 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 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
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�
Grooving (see fig. 13)
• Set the required rebate width using side stop 29
(see fig. 13.1).
• Set the required rebate height using vertical stop 23
(see fig. 13.1).
• Perform planing pressing side stop 29 against the
workpiece side surface (see fig. 13.2). Repeat the op-
eration until the desired result is reached�
Edge chamfering (see fig. 14)
V-groove 14 allows chamfering at the edges of treated
workpieces�
Incline the power tool at 45° (see fig. 14) and perform
planing� During operation special attention shall be
paid to angle of the power tool inclination and uniform-
ity of conveying�
Power tool maintenance / preventive
measures
Before carrying out any works on the power tool
remove the battery 10.
Battery maintenance instruction
• Charge timely before the battery 10 is completely
exhausted� Stop operation in low power and charge it
immediately�
• Do not overcharge when the battery 10 is full, other-
wise it will shorten the life time�
• Charge battery 10 in the room temperature of 10°C
to 40°C (50°F to 104°F)�
• Charge battery 10 every 6 months without operation
for a long time�
• Replace worn out batteries in time� Decline of pro-
duction or a significantly shorter runtime of the power
tool after charging indicates aging of the battery 10 and
the need for replacement� It should be taken into ac-
count that the battery 10 may discharge faster if the
works take place in the temperature below 0°С.
• In case of long time storage without use, it is recom-
mended to store the battery 10 at room temperature, it
should be charged to 50%�
Interchangeable blades (see fig. 15-20)
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 33.
