Transport; Working Instructions - PrimAster BTS3500 Translation From The Original Instruction Manual

Note: All bolts should be inserted from the top. Install
the lock washers and hex nuts from the underside of
the workbench.
Clamping belt/disc sander to work bench
• If your belt/disc sander is to be used as a portable
tool, it is recommended you fasten it permanently
to a mounting board that can easily be clamped to
a workbench or other stable surface. The mounting
board should be of sufficient size to avoid tipping
while belt/disc sander is in use. Any good grade
plywood or chipboard with a 3/4 in. (19 mm) thick-
ness is recommended.
• Mark holes on board where belt/disc sander is to
be mounted using holes in the base as a template
for hole pattern.
• Follow last three steps in section Mounting Belt/
Disc Sander to Workbench.
If lag bolts are used, make sure they are long enough
to go through holes in belt/disc sander base and
material the belt/ disc sander is being mounted to.
If machine bolts are used, make sure bolts are long
enough to go through holes in belt/disc sander, the
material being mounted to, and the lock washers and
hex nuts.
8.6 On/Off switch (1)
• The grinder/sander can be switched on by pressing
the green button „1".
• To switch off the grinder/sander you must press the
red button „0".
Warning: Do not reach across the sanding disc to
turn the belt/disc sander ON or OFF. Contact with the
sanding disc can result in serious personal injury.
8.7 Grinding/sanding
• Always hold the workpiece firmly during grinding/
sanding.
• Do not exert excessive pressure.
• To prevent the abrasive paper from becoming worn
on one side, the workpiece should be moved to
and from on the grindinög/sanding belt or grinding/
sanding plate as you grind/sand.
• Important! Pieces of wood should always be sand-
ed with the grain to prevent them splitting.
Important.
If the grinding wheel or the grinding/sanding belt be-
comes jammed during operation, please remove the
workpiece until the tool reaches its top speed again.

9. Transport

If you want to move the equipment to a different
place, disconnect the equipment from the power
supply and set it up in the new position you want to
use it in.

10. Working instructions

Bevel sanding, Fig. 12
The worktable can be tilted from 0° to 45° for bevel
sanding. To tilt the worktable:
• Loosen the table lock knob (3) by turning it coun-
terclockwise.
• Set worktable to desired angle.
• Note: Position the worktable not further than 1/16
in. (1.6 mm) from the sanding surface.
• Tighten the table lock knob by turning it clockwise.
Sanding small end surfaces using the miter
gauge, Fig. 13
A miter gauge (7) is included with your tool for increased
accuracy. Use of a miter gauge is recommended for
sanding small end surfaces on the sanding disc.
Note: Always move the workpiece across the sanding
disc from the left side towards the right side.
Horizontal and vertical sanding, Fig. 10+11+14
Your belt/disc sander can sand both vertically and hor-
izontally. Depending on the workpiece, the work sup-
port can be used with either the horizontal or vertical
sanding operation.
• Slacken the two nuts (29).
• Move the grinding/sanding belt (11) upwards into
the desired position.
• Retighten the nuts (29) to secure this position.
• In this position you can use the grinding/ sanding
table to support the workpiece. To do so, push the
table into the hole in the holding tube (31) and se-
cure with the screw (30).
Note: Sand long workpieces with the sanding belt in
the vertical position by moving the work evenly across
the sanding belt.
Surface sanding on the sanding belt, Fig. 15
• Hold the workpiece firmly, keeping fingers away
from the sanding belt.
• Keep the end pressed firmly against the work sup-
port (12) moving work evenly across the sanding
belt.
Note: Use extra caution when sanding very thin pieces
and when sanding extra long pieces, remove the work
support(12). Apply only enough pressure to allow the
sanding belt to remove the material.
Sanding curved pieces, see Fig. 16
Warning: Never attempt to sand the end pieces of a
workpiece on the idler drum. Applying the end of the
workpiece on the idler drum could cause the work-
piece to fly up. Failure to heed this warning could result
in serious personal injury.
Always sand inside curves on the idler drum as shown
in Figure 16.
• Hold the workpiece firmly, keeping fingers away
from the sanding belt.
• Keep the curve pressed firmly against the idler drum
moving work evenly across the sanding belt.
Note: Use extra caution when sanding very thin pieces
and apply only enough pressure to allow the sanding
belt to remove the material.
Sanding outside curves on sanding disc Fig. 17
Always sand outside curves using the sanding disc
and moving the workpiece (W) from the left side of
center as shown in Figure 17
• Hold the workpiece firmly, keeping fingers away
from the sanding disc.
• Keep the curve pressed firmly against the sanding
disc moving work evenly on the left side of the sand-
ing disc.
Warning: Applying the workpiece to the right side of
the sanding disc could cause the workpiece kickback.
Failure to heed this warning could result in serious per-
sonal injury.
