Hyd‑Mech Group Bandsaw S23

The oil level should be maintained in the upper half of the level gauge. Normally the rate of oil consumption will be very low and it should be unnecessary to add oil more often than at filter changes. Add oil only to the top line on the gauge.

In general, if the oil level is maintained and the filter is changed as recommended, there is no need to change the oil unless there are visible signs of degradation such as: Rapid darkening of oil. Milky or hazy oil colour. Varnish or sludge formation. Burnt smell from the oil.

However, if the machine is exposed to extreme temperature variation and high humidity, then the oil should be changed every 2000 operating hours or at least once a year.

To change the oil, it is necessary to drain the tank (a drain plug is found on the bottom of the tank) and fill it to 1/3 full level with the new oil, operate through several fully automatic cycles with the index set to full stroke and the head to full rise. Drain the tank again, and finally fill the tank with the new oil. Hydraulic tank capacity is approximately 8 US gallons.

Check for visible signs of oil degradation

Is the machine exposed to extreme temperature variation and high humidity?

Drain the tank and fill it to 1/3 full level with the new oil

NOTE: Wear gloves for protection from the sharp blade.

Open the Idler Wheel and Drive Wheel doors and swing the head to 45 degrees

Loosen the Blade Tensioner by turning counter clockwise

Loosen the carbide tension handles by turning counter clockwise 1/4 turn

Remove the old blade from the protective channel and guides

Measure the new blade width including the teeth

Uncoil the new blade while wearing gloves

Place the new blade in the carbide guides and over the wheels

Set the blade tension correctly by turning the tensioner handle clockwise

The clamping force on the swivel brake can be adjusted to ensure that the Head is held securely and does not move during cutting. The brake handle should be adjusted so that it does not 'bottom out' or hit it's movement limit, yet holds the head securely.

ANGLE BRAKE ADJUSTMENT PROCEDURE

Loosen locking cap screws 'B' with a 1/4 allen key.

Tighten all 4 set screws 'A' until snug with a 5/32' allen key.

Back out the 'A' screws 1/4 of a turn.

Tighten the locking cap screws 'B'.

Swing the head to 45o and back to ensure that the head moves freely and does not bind on the pivot surfaces.

Adjust the clamping force bolt 'C' with a 3/4' wrench. If not tightened enough, the locking handle will 'bottom out' and not hold the head firmly.

Warning: This procedure requires trained personnel with PPE!

Is the blade brush in contact with the blade at the bottom of the blade gullets?

Is the plastic drive wheel held against the blade face with minimum force?

As the blade brush wears, it is necessary to periodically adjust it closer to the blade.

Are there two springs on socket head screws holding the brush assembly against the blade?

Is there an adjusting socket set screw with a hex nut on it?

Loosen the hex nut with a 9/16\ wrench and turn the set screw counter clockwise with a 3/16\" allen key."

Did you adjust the set screw so that the brush cleans to the bottom of the blade gullets?

Warning: Ensure the machine is turned off and unplugged before cleaning

Control console free of dirt and grease
