Insert both planer blades into the sharpening device and
clamp them by tightening the wing bolt.
Make sure that both planer blades are completely inserted
to the stop.
Move the sharpening device with the inserted planer
blades uniformly and with light pressure across the
whetstone.
Note: Never regrind the planer blades by more than 6 mm,
based on a minimum width of 23 mm.
Thereafter, both planer blades must be replaced.
Assembling the Planer Blade(s) (see figures E–F)
Before reinserting new or resharpened planer blades,
clean the blade drum 14 and the planer blades 16, if
required, as well as the HSS planerblade retainer 17. Clean
heavily gummed planer blades with spirits or petroleum.
Note: Before assembling new or resharpened planer
blades, their correct height setting must be adjusted first.
The setting gauge 20 (accessory) is used for adjusting the
height of the planer blades. Place the planer blade 16 and
the blade retainer 17 on the setting gauge. Make sure that
the blade retainer 17 engages in the groove inteneded for
this purpose.
Press the planer blade 16 against the stop and lock the
blade retainer 17 in this position with the fastening screws
18. This will automatically adjust the correct height.
Each planer blade must be assembled and aligned centered
to the planer base plate 8. Afterwards, tighten the three
fastening screws 12 with the Torx key 11, ensuring the
correct tightening sequence (1 2 3) on the clamping jaw
13.
Note: Before starting operation, check the fastening
screws 12 for tight seating. Rotate the blade head 14
manually and ensure that the planer blades do not graze
Dust/Chip Extraction
u Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful
to one's health. Touching or breathing-in the dusts can
cause allergic reactions and/or lead to respiratory
infections of the user or bystanders.Certain dusts, such
as oak or beech dust, are considered as carcinogenic,
especially in connection with wood-treatment additives
(chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system
suitable for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
Clean the chip ejector 3 regularly. Use a suitable tool (e.g.,
a piece of wood, compressed air, etc.) to clean a clogged
chip ejector.
u Do not reach into the saw dust ejector with your
hands. They could be injured by rotating parts.

Manual GHO 26-82 D Professional.indd 20
To ensure optimum extraction of dust/chips, always work
with external dust extraction or a chip/dust bag.
External Dust Extraction (see figure G)
An extraction chip/dust bag 33 (accessory), can be
attached on either side of the chip ejector.
Connect the chip/dust bag 33 to a vacuum cleaner
(accessory). An overview for connecting to various vacuum
cleaners can be found at the end of this manual.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Integrated Dust Extraction (see figure G)
A chip/dust bag (accessory) 33 can be used for smaller
jobs. Insert the sleeve of the chip/dust bag firmly into the
chip ejector 3. Empty the chip/dust bag 33 at regulary
intervals to maintain optimum dust collection.
Choice of Chip Ejector Side
With the selector lever 6, the chip ejector 3 can be switched
to right or left. Always press the selector lever 6 until it
engages in the end position. The selected ejection direction
is indicated by an arrow symbol on the selector lever 6.
Operation
Operating Modes
Adjusting the Planing Depth
With the adjustment knob 2, the planing depth can be
adjusted variably from 0–2.6 mm using the planing depth
scale 1 (scale graduation = 0.1 mm).
Park Rest (see figure D)
The park rest 29 allows the machine to be set down directly
after operation, without danger of damaging the working
surface or the planer blade. While planing, the park rest 29
is tilted upwards thus enabling full contact of the rear part
of the planer base plate 7.
Note: The park rest 29 may not be removed.
Starting Operation
u Observe correct mains voltage! The voltage of the
power source must agree with the voltage specified
on the nameplate of the machine. Power tools
marked with 230 V can also be operated with 220 V.
Switching On and Off
To start the machine, first push the lock-off button for the
On/Off switch 4 and then press the On/Off switch 5 and
keep it pressed.
To switch off the machine, release the On/Off switch 5.
Note: For safety reasons, the On/Off switch 5 cannot be
locked; it must remain pressed during the entire operation.
Working Advice
Planing (see figure G)
Set the required planing depth and place the front part of
the planer base plate 7 against the workpiece.
u Apply the machine to the workpiece only when
switched on. Otherwise there is danger of kickback
when the cutting tool jams in the workpiece.
