Planer Blade Selection

When replacing planer blades, always replace both blades;

otherwise an imbalance can generate vibrations, which can

reduce the service life of the power tool.

Changing HSS Planer Blades

f Be cautious when replacing the planer blades. Do not

grasp the planer blades by the cutting edges. Possible

danger of injury due to the sharp cutting edges of the plan-

er blades.

Disassembling the Planer Blade(s) (see figures A–C)

– To reverse the planer blades, rotate the blade drum 13 un-

til the clamping jaw 12 is parallel to the planer base plate 1.

– Unscrew the 3 fastening screws 11 with the t-handle

wrench 10 and remove the clamping jaw 12.

– Slide the planer-blade retainer 16 together with the planer

blade 15 out of the guide groove 14 of the blade drum 13.

– Turn the blade drum by 180° and disassemble the 2nd

planer blade.

Note: Before replacing or resharpening the planer blades, re-

move the HSS planer-blade retainer 16 by loosening the fas-

tening screws 17.

Resharpening HSS Planer Blades (see figure D)

Worn or dull HSS planer blades can be resharpened with the

sharpening device 18 (accessory) and a commercially availa-

ble whetstone.

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 13 and the planer blades 15, if required, as

well as the HSS planer-blade retainer 16. 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 19 (accessory) is used for adjusting the

height of the planer blades. Place the planer blade 15 and the

blade retainer 16 on the setting gauge. Make sure that the

blade retainer 16 engages in the groove inteneded for this

purpose. Press the planer blade 15 against the stop and lock

the blade retainer 16 in this position with the fastening

screws 17. This will automatically adjust the correct height.

Each planer blade must be assembled and aligned centered

to the planer base plate 1. Afterwards, tighten the three fas-

tening screws 11 with the t-handle wrench 10.

Note: Before starting operation, check the fastening screws

11 for tight seating. Rotate the blade head 13 manually and

ensure that the planer blades do not graze.

Dust/Chip Extraction

f 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-treat-

ment additives (chromate, wood preservative). Materials

containing asbestos may only be worked by specialists.

– As far as possible, use a dust extraction system suita-

ble 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 5 regularly. Use a suitable tool (e.g., a

piece of wood, compressed air, etc.) to clean a clogged chip

ejector.

f Do not reach into the saw dust ejector with your hands.

They could be injured by rotating parts.

Operation

Operating Modes

Adjusting the Planing Depth

With the adjustment knob 3, the planing depth can be adjust-

ed variably from 0–2.0 mm using the planing depth scale 4

(scale graduation = 0.25 mm).

Park Rest (see figure G)

The park rest 21 allows the machine to be set down directly

after operation, without danger of damaging the working sur-

face or the planer blade. While planing, the park rest 21 is tilt-

ed upwards thus enabling full contact of the rear part of the

planer base plate 1.

Starting Operation

f Observe correct mains voltage! The voltage of the pow-

er 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, press the On/Off switch 7 and keep it

pressed.

To lock the pressed On/Off switch 7, press the lock-on button

To switch off the machine, release the On/Off switch 7 or

when it is locked with the lock-on button 6, briefly press the

On/Off switch 7 and then release it.

Working Advice

Planing (see figure G)

Set the required planing depth and place the front part of the

planer base plate 1 against the workpiece.
