6. MAINTENANCE OF MACHINE
Open the rear cover and inspect the following parts every week.
No. Inspecting Item
1. If the variable speed pulley runs freely?
2. If the air way of the air injection is blinded?
3. If the oil level of transmission is too low?
4. If the grease is supplied at the shaft of variable speed pulley?
No. Trouble-Shooting
1. Please inspect and lock the screw of variable speed pulley. Little vib-
ration and noise is normal.
2. Clear the blinding with an air compressor.
3. Replace or make up with “Shell Tellus Oil 69”. It should be done that
change the lubrication oil once in 6 months.
4. Apply grease (Shell Alvania Grease 2) with a grease gun until it
shows up at the space between variable speed pulley and shaft.
7. STANDARD ACCESSORIES
1. Small tool set
Grease gun
1 pc.
Double head sSpanner 10x12 1 pc.
12x14 1 pc.
Screw 1 pc.
Screw driver – 1 pc.
Socket Hd. screw spanner 4 mm 1 pc.
5 mm 1 pc.
6 mm 1 pc.
8 mm 1 pc.
2. Saw blade ready for use 1 pc.
3. Working lamp 1 pc.
4. Saw blade welder 1 set.
5. Electro-magnetic switch 1 set.
6. Motor over load protection 1 set.
7. Low voltage control circuits 1 set.
4. Set the “Upset Force Selector” at “0”.
5. Align and fix both ends of saw blade between both electrodes which are
at the center of two pole jaws.
6. Adjust the “Upset Force Selector” to proper position according to the
width of saw blade. (The relative position which the width of saw blade
is equivalent to the sign.)
CAUTION!
Do not operate without eye protection
7. Push the upper right Welding Button, Never release until the fire is
extinguished and circuit broken.
8. Loosen the saw blade and return the Upset Force Selector “0”.
Annealing operating
1. When the welding is finished, saw blade should be locked again to the
front wide part of pole jaws. At this time, annealing should be situated
at the intermediate position of pole jaws.
2. Push the Annealing Push Button, release it until the saw blade turn into
orange color (750°C-780°C). Repeat the process 2-3 times.
3. After annealing, the saw blade must be dressed to remove excess metal
or flash from the weld. Grind the welded area to the same thickness as
the rest of saw blade.
4. Again welded blade is locked to pole jaws annealing should be repea-
ted by the same way as article 2. But in this case it must be operated at
little lower temperature than article 2 case.
Special caution for operation
1. This welder is designed for band saw blade welding only. It must not be
used on non-ferrous metals.
2. Blade must be cleaned of all dirt, oil, scale and oxide before welding.
3. The pole jaws of the welder must be kept clean.
4. When the polw jaws are uneven, adjust, grinding or replace it with a
new one is required. Never hammer it.
5. Turn off power supply when the grinding wheel is not employed.
6. Turn off the welding lamp during annealing in order to examine the
change of colors of saw blade.
