■Connect machines that are used in the open via a residual current device (RCD) with an ac- tuating current of 30 mA maximum. Use only extension cables that are approved for outdoor use.
■Always direct the cable to the rear away from the machine.
■Apply the machine to the workpiece only when switched on.
■Use only sharp planing blades.
■Always hold the machine firmly when working and ensure a secure stance.
■Keep hands away from rotating parts.
■The planer shoe 13 must lay flat on the surface when working.
■Never plane over metal objects such as nails or screws.
■Do not allow fingers to enter the chip ejector 3.
■Always switch off the machine and allow to come to a stop before placing it down.
■For stationary use as a surface or panel planer with appropriate accessories.:
-Pull the mains plug before mounting.
-Use the
-Work small workpieces only with a suitable feeding device, e. g. a piece of wood.
-use the switching device belonging to the ac- cessory.
■Never allow children to use the machine.
■Bosch is only able to ensure perfect operation of the machine, if the original accessories in- tended for it are used.
Initial Operation
Observe correct mains voltage: The voltage of the power source must agree with the voltage specified on the nameplate of the machine. Equipment marked with 230 V can also be con- nected to 220 V.
Switching On and Off
To start the machine, press the safety switch against starting 8 first, then press and hold the On/Off switch 7.
To switch off the unit, release the On/Off switch 7.
For safety reasons the On/Off switch of the machine cannot be locked; it must remain pressed during the entire operation.
Constant Electronic Control/Electronic Soft Start (GHO
The integrated constant electronic control keeps the speed almost constant, even under load. This compensates varying planing pressure and cut- ting depth. The electronic soft start increases working life of motor and drive belt.
Motor Protection (GHO 36-82 C)

Adjusting the Planing Depth
The planing depth can be adjusted variably from 0 – 3.1 mm (GHO
Rotation in counterclockwise direction 
= reduces the planing depth
Rotation in clockwise direction 
= in- creases the planing depth
Chip Vacuuming (see figure A )
■Before any work on the machine itself, pull the mains plug.
The dust that is produced while working can be detrimental to health, inflammable or explo- sive. Suitable safety measures are required.
Examples: Some dusts are re- garded as carcinogenic. Use suitable dust/chip extraction and wear a dust mask.
Clean the chip ejector 3 regularly. Use a suitable tool (e. g. piece of wood, compressed air, etc.) to clean clogged chip ejector. Do not allow fingers to enter the chip ejector 3.
To ensure optimum extraction of sawdust/wood chips, attach the vacuum hose 21 or the sawdust /wood chip bag 22 tightly onto the chip ejector 3.
