7. Open the valve on the hydraulic cylinder to allow the bow to descend in a gradual and controlled manner.

9. Return the bow to vertical position for the next cut.

Maintenance

Before doing maintenance
on the machine, disconnect it from the
electrical supply by pulling out the plug or
switching off the main switch. Failure to
comply may cause serious injury.
Clean the band saw regularly after each day’s
work. Clear metal shavings with the provided
brush, do not use your hands. Do not use
compressed air.
To prevent corrosion of machined surfaces
when a soluble oil is used as coolant, pay
particular attention to wiping dry the surfaces
where fluid accumulates and does not evaporate
quickly, such as between the machine bed and
vise.
If the power cord is worn, cut, or damaged in
any way, have it replaced immediately.
All ball bearings are permanently lubricated and
sealed. They require no further lubrication.
Grease the vise lead screw as needed.
Place a thin coat of oil on the bed surface on
which the vise jaw slides.
Maintain coolant level. Low coolant level can
cause foaming and high blade temperatures.
Replace dirty coolant; dirty or weak coolant can
clog the pump, cause crooked cuts, a low
cutting rate and/or permanent blade damage. To
fill the tank, remove the filter cup and pour
coolant into the hole. A “Hi/Lo” mark on the tank
indicates proper level (see Figure 5).
Maintain oil level in the gear box, using SAE No.
10. To check level of the gear box oil, place bow
in down position so that oil drains down. Check
level in sight glass on side of gear casing.
Correct level is the dot in the middle of the sight
glass. Figure 24 shows the locations of the fill
hole, sight glass and drain plug for the gear box.
Completely drain and refill the gear box oil once	Figure 24
a year.
