Adjusting The Cutting Depth - Mafell SG 230 Manual De Instrucciones

4 Operation
4.1 Operating instructions
The distance of the cut to be made parallel to the
edge of the timber can be set by adjusting parallel
guide fence 6 (Fig. 1).
• To adjust parallel guide fence 6 loosen wing
screws 7 (Fig. 2) and set the distance by means
of scale 4.
• After adjusting, retighten the wing screws 7. Par-
allel guide fence 6 (Fig. 1) can also be used as
an extended support; simply turn it over.
The distance of a cut at a right angle to the edge of
the timber can be determined by adjusting stop
bows 9 (Fig. 2).
• Loosen wing screw 10 (Fig. 1) and adjust the dis-
tance.
• Then retighten wing screw 10.
When doing horizontal cuts the weight compensat-
ing spring 41 (Fig. 3) may be released to facilitate
the cutting operation.
• Locking bolt 40 has to be turned counterclockwise
as far as it will go (the flat part at the knurl is in
vertical position) and after completion of the cut-
ting operation the locking bolt has to be turned
back.
With slot lengths exceeding 50 mm
(1 31/32 in.) begin mortising at the right
marking. When the first cut has been
completed, pull out the machine, move it
sideways to the left and make the sec-
ond cut.
4.2

Adjusting the cutting depth

The cutting depth is continuously adjustable.
• Loosen wing screw 12 (Fig. 2) and move depth
stop ring 13 to the depth required.
• Retighten 12 wing screw.
4.3 Securing the machine against moving
sideways
When mortising vertically positioning pin 11 (Fig. 1)
serves as a safety device to prevent that the slot
mortising device is moving sideways. This position-
ing pin will perform its function once it is completely
screwed into the base plate.
5 Maintenance
The roller bearing of the chain bar should be kept
well greased. Grease gun 15 (Fig. 2) is provided for
this purpose which should be pressed into the hole
at the tip of the bar (only acid-free ball bearing
grease of good quality should be used)!
The chain should be immersed in thin oil every time
it has been resharpened. When the chain is being
used very frequently it should be oiled several times
a day!
Before re-tensioning the chain let it cool down.
