Speed Adjustment - Scheppach DM460T Traduction Du Manuel D'origine

• Trim work piece to a rectangular shape, center and
correctly secure before processing. Unbalanced work
pieces can be hazardous.
• Injuries can occur when feeding work pieces if tool sup-
ports are not correctly adjusted or if turning tools are
blunt. Sharp turning tools which are free of defects are
necessary for professional turning.
• Long hair and loose clothing can be hazardous when
the work piece is rotating. Wear personal protective
gear such as a hair net and tight fitting work clothes.
• Saw dust and wood chips can be hazardous. Wear pe-
sonal protective gear such as safety goggles and a dust
mask.
• The use of incorrect or damaged mains cables can lead
to injuries caused by electricity.
• Even when all safety measures are taken, some re-
maining hazards which are not yet evident may still be
present.
• Remaining hazards can be minimized by following the
instructions in „Safety Precautions", „Proper Use" and in
the entire operating manual.
Start-up
Observe the safety notes in the operating instructions
before operating the machine.
Remove the tensioning spindle or the chuck from the
spindle in addition to any step-up tools before first
operating the machine!

Speed adjustment

The speed can only be adjusted once the machine has
been unplugged.
The correct number of revolutions is visible on the speed
diagram located on the headstock. The speed diagram is
intended for medium-hard dry woods.
The appropriate speed is based on various factors such
as:
• type and compostion of woods
• seasoned, dry woods
• diameter and length of workpieces
• squared or unbalanced woods
• width of pre-worked, balanced workpieces
• wood turner tools and technique
• workpieces out of glued wood
Successful wood turning does not result from high speeds,
but rather, from correct use of the machine.
Guidelines for speed adjustment
Low speeds for:
• workpieces with large diameters
• hard workpieces with large diameters
• long, unbalanced workpieces
• glued pieces of wood
Speed adjustment (Fig. 2+3)
• Open casing by rotating the lock screw of a revolution to
the left.
• Loosen the socket-head screw (C).
• Using the lever, raise the electric motor and move the
belt to the desired level. The belt must lie exactly in the
grooves of the belt disc.
• Lower the electric motor into place and tighten the belt
by applying light pressure to the lever (2). Tighten the
socket-head screw (C).

NOTE: Extremely high belt-tension causes rapid wear of
the belt.
• Close the casing and lock into place by turning the
screw of a revolution to the right.
• When the cover is closed, read the adjusted speed from
the viewing-window.
• When working with highly unbalanced workpieces, se-
lect a speed at least one level lower.
Driver, Fig. 1.1, 5
The driver is used exclusively for work between both centers.
Face plate, figure 1.1, 2
The face plate is used with flat larger tools.
Change of the clamping tools
• Loosen grub screw on the shaft of the clamping tool.
• Retain spindle with mandrel, release the clamping tool
with the hexagonal spanner.
Tailstock, Fig. 1.1, 6
• Once the eccentric clamp has been loosened, the tail-
stock can be moved over the entire length of the bed
and can be secured at any distance from the headstock.
• To insert a workpiece between the centers, loosen the
binder, turn the sleeve approx. 20 mm outward and
clamp.
• Slide the tailstock to the workpiece and place the tail-
stock center into the sunken point in the center of the
workpiece.
• Screw out the tailstock sleeve until the tailstock center
rests securely in the wood. Retighten the binder.
• Turn the workpiece to see if it rests securely between
the two centers and can be rotated freely.
Tailstock center replacement, Fig. 1.1, 4
• Turn tailstock spindle sleeve totally backwards until the
tip can be removed.
Tool holder, Fig. 1.1, 3
• The tool holder both insures safe use of wood turning tools
and at the same time serves as a support for the hand.
The height of the tool holder can be adjusted once the
binder has been loosened. To turn further, pull in the
direction indicated by the arrow.
• Place the tool holder at a distance of 1 – 3 mm from the
workpiece. Check the adjustment in addition to rotating
the workpiece by hand.
• Set the tool holder ca. 3 mm above the axis of the workpiece.
Check the adjustment once again by rotating the work-
piece by hand.
• Once the eccentric clamp has been loosened, the hold-
er console can be moved along the entire length of the
bed and in the direction perpendicular to the workpiece.
Furthermore, the holder console can be tilted over ap-
prox. 45º to either side.
• To work with a plane surface, turn the tool holder 90º
and place up against the surface to be worked. De-
pending on the wood turning tool, place the tool holder
up to 6 mm underneath the axis of the workpiece.

most frequent forms. Once the machine has been plugged
in, it is ready to be used. Observe the operating instruc-
