How To Use The Belt Sander; Maintenance And Inspection - Metabo HPT SB 8V2 Instrucciones De Manejo

English
1. How to attach sanding belt
(1) Pull lever with fi nger, idle pulley will then move
backward. (Fig. 1)
(2) Place on drive pulley and idle pulley passing it over the
outside of shoe plate and making sure that arrow on
inside of belt coincides with rotational direction of drive
pulley. (Fig. 2)
(3) Push lever with fi nger, idle pulley will then move forward
and give proper tension to sanding belt.
In this case, be careful not to be hit your fi nger by lever.
Then, adjust sanding belt position.
CAUTION:
Sanding belt installed in the wrong direction will lower
work effi ciency and shorten life of sanding belt.
2. How to remove sanding belt
Pull lever with fi nger, sanding belt will then sag and can
be taken off pulleys eqsily.
DUST REMOVAL
When an excessive amount of dust is deposited in the dust
bag, dust-collecting effi ciency will sharply drop.
Remove dust from the bag when it is deposited up to about
2/3 the bag capacity, where by dust collecting effi ciency (as
well as working effi ciency) will be ensured.
Remove dust from the bag as follows:
(1) Loosen the support bar and remove the dust bag.
(Fig. 5)
(2) The bag inlet can be opened by unzipping the slide
fastener.

HOW TO USE THE BELT SANDER

1. How to adjust sanding position.
Push switch and turn sanding belt te check position.
Adjust sanding belt so that both edges protrude
1.6mm – 3mm past edges of pulleys.
lf sanding belt is operated too far on the inside, it may
ceuse abrasion and damage machine.
Adjust sanding belt position by turning adjust screw.
(Fig. 3)
○ Turn adjust screw clockwise to move belt in.
○ Turn adjust screw counterclockwise to move belt out.
CAUTION:
If sanding belt moves during operation, adjustment can
be made while in operation.
2. To turn on switch
Turn on switch while holding machine away from surface
to be worked on. If machine is placed on surface when
switch is pushed, surface may be badly scratched.
The same applies when stopping the machine.
3. How to hold machine
Grasp handle and handle knob and hold machine
against surface to be worked on so that it contacts
surface lightly.
Weight of machine itself is suffi cient for sanding and
polishing at highest effi ciency.
Do not apply any additional pressure, for this would
place unnecessary load on motor, shorten life of
sanding belt and lower work effi ciency.(Fig. 4)
4. How to move machine
Move mechine forward fi rst and then backward,
repeating this motion.(Fig. 4)
5. How to select proper sanding belt
Choose sanding belt of proper grain size and grain type
for your specifi c purpose, by referring to Table 2 and 3
below.

CAUTION:
○ For grain sizes, refer to Table 3
○ Sanding belt grain should be coarser than sandpaper
used for manual work.
○ Use sanding belt of same grain size until uniform
surface is obtained. Changing grain sizes may result in
poor fi nish.
6. How to operate switch
The power switch is turned ON when the trigger is
pulled, and if the stopper is once depressed, the power
switch becomes locked, allowing continuous operation.
The stopper can be released pulling the trigger. (Fig. 5)
7. Adjusting the belt speed
The Belt Sander is equipped with the electric control
circuit which enables stepless speed control. To adiust
the speed, turn the dial shown in Fig. 6.
When the dial is set to "1", the belt sander operates at
the minimum speed. When the dial is set to "5", the belt
sander operetes at the maximum speed.
8. How to work on corner
Corners can be sanded and polished by using machine
as in Fig. 7.

MAINTENANCE AND INSPECTION

1. Inspecting the sanding belt
Since continued use of a worn-out sanding belt will
degrade effi ciency, replace the sanding belt as soon as
excessive abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do so
could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the power
tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes
For your continued safety and electrical shock
protection, carbon brush inspection and replacement
on this tool should ONLY be performed by a metabo HPT
Authorized Service Center.
5. Replacing supply cord
If the supply cord of Tool is damaged, the Tool must be
returned to metabo HPT Authorized Service Center for
the cord to be replaced.
