Switching On/Off; Practical Advice; Maintenance And Servicing; Maintenance And Cleaning - Bosch GHO 6500 Professional Notice Originale

Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.

Switching on/off

Make sure that you are able to press the On/Off switch
u
without releasing the handle.
To start the power tool, first press the lock-off button for on/
off switch (4), then press and hold the on/off switch (5).
To switch off the power tool, 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.

Practical advice

Pull the plug out of the socket before carrying out any
u
work on the power tool.
Planing Procedure (see figure N)
Set the required cutting depth and position the power tool
with the front section of the planer base plate (8) on the
workpiece.
Only bring the power tool into contact with the work-
u
piece when switched on. Otherwise there is danger of
kickback if the cutting tool jams in the workpiece.
Switch on the power tool and guide it over the surface of the
workpiece, applying uniform feed.
To achieve high-quality surfaces, apply only a low feed rate
and exert pressure on the middle of the planer base plate.
For the processing of hard materials, such as hardwood, and
also when utilising the maximum planing width, set only a
low cutting depth and reduce the planer feed as appropriate.
Excessive feed reduces the quality of the surface finish and
can lead to the chip ejector quickly becoming blocked.
Only sharp planer blades achieve good cutting performance
and make the power tool last longer.
The integrated parking rest (29) also enables a continuation
of the planing procedure following interruption at any point
on the workpiece:
– Place the power tool – with parking rest folded down –
onto the area of the workpiece that you will continue to
work on.
– Switch the power tool on.
– Shift the contact pressure onto the front of the planer
base plate and slowly slide the power tool forward (➊). In
doing so, the parking rest will swivel upwards and out of
the way (➋), meaning that the rear section of the planer
base plate is in contact with the workpiece again.
– Guide the power tool over the surface of the workpiece,
applying uniform feed (➌).
Chamfering edges (see figure O)
The V-grooves in the front of the planer base plate enable
quick and easy chamfering of workpiece edges. Select the V-
groove that corresponds to your chamfering width. Then po-
sition the planer with the V-groove onto the edge of the
workpiece and guide it along.

Planing with the Parallel/Angle Guide (see figures K–M)
Attach the parallel guide (21) or the angle guide (25) to the
power tool with the fastening screw (24). Depending on the
application, attach the rebate depth guide (28) to the power
tool with the fastening screw (27).
Loosen the locking nut (23) and set the desired rebate width
on the scale (22). Retighten the locking nut (23).
Set the desired rebate depth accordingly using the rebate
depth guide (28).
Carry out the planing procedure several times until the de-
sired rebate depth has been achieved. Guide the planer with
sideways contact pressure.

Maintenance and Servicing

Maintenance and cleaning

Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
Keep the parking rest (29) clear and clean it regularly.
When the carbon brushes are worn out, the power tool
switches itself off. The power tool must be sent to the after-
sales service for maintenance; see the "After-sales service
and advice on using products" section for addresses.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by a
customer service centre that is authorised to repair Bosch
power tools.
Changing the Drive Belt (see figures P–Q)
Unscrew the screw (6) completely and take off the belt
cover (7). Remove the worn drive belt (30).
Before fitting a new drive belt (30), clean the two belt
wheels ((31) and (32)).
First place the new drive belt (30) onto the small drive wheel
(32), and then press the drive belt (30) onto the large drive
belt (31), turning it by hand.
Make sure that the drive belt (30) runs exactly in the length-
ways grooves in the drive wheels ((31) and (32)).
