Metalworking
Take the following safety precautions when cutting metals:
- connect a residual current operated device in series before
the tool,
- connect tool to a suitable dust extractor,
- clean tool regularly of dust accumulations in the motor
housing.
Extension cord
If an extension power cord is required, it must have sufficient
cross-section to prevent an excessive drop in voltage or
overheating. An excessive drop in voltage reduces the output
and can lead to failure of the motor. The table shows the
correct size to use, depending on cord length and the tools
ampere rating. Use only U.L. and CSA listed extension cords.
Never use two extension cords together. Instead, use one
longer one.
Note: The lower the A.W.G. number, the thicker the cord.
Tool settings
Always disconnect the plug from the power
supply before making any adjustments to the tool or installing
or removing any accessory!
Electrical connection and operation
The mains (supply) voltage must correspond to the voltage
on the rating plate!
Always switch the tool off before connecting or
disconnecting the power cord to the tool or to a power socket!
See Fig. 2 for connecting or disconnecting the power cord to
the tool.
The PS 300 EQ has a slide switch (1.1) to switch the tool on
and off (I = ON, 0 = OFF).
The PSB 300 EQ has a pushbutton switch (1.1) to switch the
tool on and off. This can be locked with the locking button
(1.8) for continuous operation. Press the pushbutton switch
again to release the lock.
Electronic control
The PS 300 EQ and PSB 300 EQ have control electronics which
enable stepless adjustment of the stroke rate between 1000
and 2900 strokes per minute. The desired stroke rate is set
with the speed controller (3.1):
Setting 1 = 1000 strokes per minute,
Setting 6 = 2900 strokes per minute.
Recommended stroke rate (speed controller setting):
Hard and soft wood, wood core plywood: 6
Plywood, chip board: 6
Wood fiberboard: 4-6
Plastics: 3-6
Ceramic: 3-5
Aluminum, NF metals: 3-5
Steel: 2-4
