MHB158 MHB158E - Service

ENGLISH
• Before replacing the top cover of the mains plug
ensure that the cable restraint (3) is holding the
outer sheath of the cable firmly and that the two
leads are correctly fixed at the terminal screws.
Never use a light socket.
Never connect the live (L) or neutral (N)
wires to the earth pin marked E or .
For 115 V units with a power rating exceeding 1500 W,
we recommend to fit a plug to BS4343 standard.
Using an extension cable
If an extension cable is required, use an approved
extension cable suitable for the power input of this
tool (see technical data). The minimum conductor size
is 1.5 mm 2 . When using a cable reel, always unwind
the cable completely. Also refer to the table below.

Assembly and adjustment
Prior to assembly and adjustment always
unplug the tool.
Fitting and centring the sanding belt (fig. B & C)
Your belt sander uses 75 x 480 mm sanding belts.
• Pull the clamping lever (12) forwards.
• Remove the sanding belt (5).
• Place a new sanding belt making sure that the
arrow on the inside of the sanding belt points in
the same direction as the arrow on the machine
when on the same side of the rollers.
• Push the clamping lever back.
• Switch the machine on and turn the belt centring
knob (6) until the sanding belt is centred on the
roller (10).
MHB158E - Speed control (fig. D)
• Turn the speed control dial (2) to the desired
position. The higher the number, the higher the
belt speed.
Mounting, removing and adjusting the sanding
frame (fig. A & E)
The sanding frame is available as an option.
• Remove the locking shaft (13) from the sanding
frame (14) and disassemble the nut, the spring
and the crankshaft (15).
• Push the locking shaft into the hole (11) at the
side where the clamping lever (12) is.
• Mount the spring, the crankshaft and the nut.
• Set the crankshafts at right angles with the
sanding belt and push the sanding frame onto
the crankshaft.
• Click the locking shaft (16) into the clamping
spring (4).
• Adjust the height of the sanding frame (14) using
the knob (17).
• To remove the sanding frame, proceed in reverse
order.
If the sanding frame is not being used, the
locking shaft (13) can be rotated a quarter
of a turn. It is not necessary to remove the
locking shaft because the crankshaft will
park inside the recess (11).
