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. 6)
• Set the required rebate width using side stop 12
(see fig. 6).
• Set the required rebate height using vertical stop 13
(see fig. 6).
• Perform planing pressing side stop 12 against the
workpiece side surface� Repeat the operation until the
desired result is reached�
Edge chamfering (see fig. 7)
V-groove 2 allows chamfering at the edges of treated
workpieces�
Incline the power tool at 45° (see fig. 7) 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 it
must be disconnected from the mains.
Do not draw up the fastening elements
too tight
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 22.
Interchangeable blades (see fig. 8-12)
[CT14019X]
Blades 24 are sharpened from both sides and their
design do not provide for their re-sharpening� In case
one blade edge becomes blunted blades 24 should be
turned, if both blade edges become blunted blades 24
should be replaced� Hereinafter referred to as "inter-
changeable blade"�
• Adjust the planing depth to "0"�
• Turn the power tool over and loosen clamping
bolts 22 using wrench 15 (see fig. 8).
• Using the wrench 15 move the interchangeable
blade 24 to the side and extract it, as shown in fig. 9.
• Replace interchangeable blade 24 or turn it over (if
the second cutting edge of the blade is sharp enough)
as shown in fig. 10.1.
to avoid damaging
• Install the interchangeable blade 24 in place, as
shown in fig. 10.1.
• Put a metal ruler to the side surfaces of base
plates 1 and 9 and align the side part of interchangeable
blade 24 (see fig. 10.2).
• Put the metal ruler to the top surfaces of base
plates 1 and 9 and make interchangeable blade 24
touch the ruler in the upper point by turning adjusting
bolts 26 with the Allen key 25 (see fig. 11), but drum 23
shall be able to turn� Ensure that interchangeable
blade 24 is adjusted in a similar way throughout all its
length (interchangeable blade 24 cutting edge shall
be parallel to the surface of front base plate 1)�
• Tighten clamping bolts 22 with wrench 15 until it
locks all detail in the slot of drum 23 (see fig. 12).
• Repeat the above operations for the second
interchangeable blade 24�
Resharpenable blades (see fig. 13-15)
[CT14019]
Resharpenable blades 32 may be resharpened�
When the blade edges become blunted resharpen-
able blades 32 should be dismantled, resharpened
by means of a special device� Then they should be
aligned and reinstalled on drum 33� Hereinafter re-
ferred to as "blades"�
• Turn the power tool over and unscrew bolts 22 using
box wrench 18 (see fig. 13).
• Remove cover 29 and blade 32 assembled with
adjusting plate 30�
the
• Unscrew screws 31 and remove adjusting plate 30
from blade 32�
• Clean all parts using a soft brush�
• Sharpen blades 32 as described below�
• Before installation of a new blade 32 make alignment
using blade alignment fixture 17�
• Place blade 32 on blade alignment fixture 17 (see
fig. 14.2). Attention: blade alignment fixture 17 has
factory setting and does not require any additional
adjustment.
• Align the cutting edge of blade 32 along the lug of
blade alignment fixture 17� Press the vertical part of
adjusting plate 30 to the vertical surface of blade align-
ment fixture 17 as shown in figure 14.2. Match the
holes in adjusting plate 30 with the holes in blade 32
moving adjusting plate 30 along blade alignment fix-
ture 17� Tighten screws 31� If the length of blade 32
is not sufficient for alignment due to multiple re-
sharpening both blades 32 must be replaced.
• Place blade 32 assembled with adjusting plate 30 on
drum 33 as shown in figure 14.3.
• Put a metal ruler to the side surfaces of base plates 1
and 9 and align the side part of blade 32 (see fig. 15.1).
• Place cover 29 and tighten bolts 22 using box
wrench 18 (see fig. 15.2).
• Repeat the above operations for the second blade 32�
Sharpening of the resharpenable blades (see
fig. 14.1)
[CT14019]
Always sharpen both blades 32 at the
same time and only using blade sharpen-
ing device 16, as this will ensure the right
sharpening angle.
