Service & Maintenance; Optional Accessories - Scheppach MJ 180 Originalbetriebsanleitung

• Whenever clamping objects with the moving jaw
reversed, ensure the workpiece sits down onto
the sliding jaw, and is parallel to it. Avoid clamp-
ing workpieces at the top of the jaws (with a gap
between the workpiece and the base of the moving
jaw) as excessive pedal pressure could damage
the unit.
• When clamping large or heavy materials, provide
outboard support (such as a trestle) to prevent
multi purpose working station from tipping over.
Clamping workpieces up to 956mm can be achieved
by removing the jaw facings (see removing the ure-
thane jaw facings). Fig. 24
USING AS AN ANVIL (Fig. 25, 26)
The fixed jaw is sufficiently robust to be used as an
anvil for strip metal work.
Do not use the moving jaw as an anvil. You could dam-
age it.
USING AS A PRESS (Fig. 27)
When the lock / release switch (13) is in the release
position multi purpose working station can be used as
a press.
With each full stroke of the foot pedal, the moving jaw
will advance about 25mm.
GENERAL OPERATING ADVICE
When working along the line of the jaws, place your
foot on the foot plates (7) to prevent multi purpose
working station from moving.
Ripping A Plank (Fig. 28-29)
1. When ripping a plank, stop your cut before reach-
ing the jaws.
2. Remove the workpiece and re­clamp with sufficient
amount of the cut beyond the jaws, so that you can
drop in your saw to recommence your cut.
3. Before clamping, insert a spacer slightly thicker
than your saw cut, at the jaw area, to keep the cut
open.
Clamping Square Tubing (Fig. 30)
It is easier to hacksaw square tubing or similar on the
diagonal.
Use the V­grooves in the urethane jaws to securely
hold your material.
Sharpening Chainsaws (Fig. 31)
multi purpose working station makes an ideal clamp to
hold a chainsaw or chainblade while sharpening the
teeth.
If sharpening a chainsaw use two wooden blocks, ei-
ther side of the bar, to ensure the clamping jaws are
clear of the chain, which can then be rotated as each
tooth is filed.

7. SERVICE & MAINTENANCE
• Any damage to multi purpose working station
should be repaired and carefully inspected before
use, by qualified repair personnel.
• Servicing should only be carried out using original
scheppach replacement parts.
• The manufacturer will not be responsible for any
damage or injury caused by unauthorized repair or
mishandling of the machine.
REMOVING THE URETHANE JAW FACINGS
(Fig. 32-35)
The jaw facings can be removed to achieve a greater
clamping range, or for replacement if worn or dam-
aged.
1. The fixed jaw facing (1) is removed by prying it off
the fixed jaw (14) using a screwdriver or similar.
Fig. 32
2. To remove the moving jaw facing, push the back-
ing face to the right (when viewed from the front
of multi purpose working station) to disengage the
connection pins. The backing face can then be re-
moved, allowing the front to be pulled off the mov-
ing jaw.g. 33,34
The pawl carrier pivot pin may occasionally require
a small amount of spray lubricant, as shown Fig.
35, if it doesn't pivot smoothly.

8. OPTIONAL ACCESSORIES

LOG AND POLE GRIPPING JAWS (Fig. 36)
Suitable for gripping logs or poles, these jaws also bolt
onto the standard steel jaws and are formed from steel
plate, zinc plated for corrosion resistance. Logs or
poles up to 175mm in diameter are gripped firmly for
chain sawing, drilling, rebating etc.
