Hyd‑Mech Group Bandsaw S-25A

The S-25A series design should endure heavy operating conditions and provide the customer with flawless machine performance. To extend good performance some care is required, especially cleanliness.

The following areas should be kept clean of dirt, grease and chips:

-LARGE BUILD UP OF CHIPS IN THE SAW BASE

Warning: This maintenance check requires trained personnel with PPE!

Is the blade brush worn out to approximately 70% of its original diameter 3 \ OD?"

If the blade brush is worn out, replace it. A brush may be purchased through a HYD-MECH dealer in your area.

Did you loosen the nut on the adjusting screw?

Did you turn the screw counter clockwise until wires from the brush touch the bottom of the blade gullets?

OIL LEVEL - 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 level gauge.

The S-25A is shipped from the factory with Valvoline 150-46 hydraulic oil. Generally any brand of recognized mineral hydraulic oil with the same properties should be compatible with Valvoline 150-46, but to avoid any risk we suggest staying with Valvoline 150-46.

If it is desired to change brands, it is necessary to drain the tank and 1/3 refill it with the new oil, operate through several automatic cycles with the index set to full stroke and head to full rise, drain the tank again, and finally fill the tank with the new brand.

Hydraulic tank capacity is approximately 17 US gallons.

OIL TEMPERATURE - Oil temperature is indicated by a thermometer contained in the level gauge.

Oil temperature during steady operation should stabilize at about 50 - 55 F° above room temperature. Thus in a 70 F° shop one might expect an oil temperature of about 120 F°. Oil temperature should never exceed 160 F°.

SYSTEM PRESSURE - System pressure is factory set to 900 ± 25 psi and should not require further attention except precautionary observation at start-up and occassionally thereafter.

BLADE TENSION - Is controlled by system pressure.

VISE PRESSURE - Is controlled by system pressure. If machine is equipped with the optional variable vise pressure; vise pressure is operator adjustable.

Select manual mode and raise the head slightly (about two inches at the drive side guide arm)

Release the blade tension by positioning the blade tension selector switch to '-'

Push the blade out from between the carbide guides

Install a new blade. The teeth should be facing away from the head of the saw. The teeth on the part of the blade between the two guide blocks should point towards the drive side of the head
