MAINTENANCE
CHANGING BELT
1.
Belts on the spindle pulley and motor pulley will
stretch during use. This stretch is taken up by
tighten the belt tension screw located below the
drive motor.
2.
To replace the belts:
(a)
Turn the belt tension
screw
counterclockwise
to relax belt tension;
(b)
Remove the old belts.
Drive Components.
3.
Install the new belts around the spindle pulley and
motor pulley. Then turn the belt tension screw
clockwise
to tighten belt so there is very little
deflection of the belts at the midpoint between the
pulleys.
ELECTRIC MOTORS
1.
Follow the manufacturer’s maintenance instructions
for each electric motor.
HEAD COMPONENTS
1.
Wipe oil onto the post occasionally. Then move the
post up and down through the slide block several
times.
2.
Oil the upper bandwheel slide and band tension
screw each month.
3.
Upper spindle bearings are sealed and lubricated
for life.
HYDRAULIC BRAKES
1.
Inspect the brake pads occasionally and keep the
pads clean. Do not allow hydraulic fluid to drip onto
the brake pads.
Hydraulic Brakes.
2.
To replace the brake pads:
(a)
Remove the housing;
(b)
Remove the nut and screw or snap ring holding
the brake pad onto the housing;
(c)
Replace the
brake pads and reinstall necessary hardware (pad
on the piston side “floats” in the opening and is not
attached);
(d)
Reinstall the housing.
3.
Remove air in the brake lines by loosening the top
screw on the brake cylinder until fluid appears.
Repeat the procedure for all brake units.
4.
Check the hydraulic reservoir for proper oil level,
add if necessary. Drain, flush, and refill the
reservoir after the first month, every six (6) months
thereafter.
HYDRAULIC SYSTEM
1.
Keep the hydraulic reservoir filled at all times.
Check the reservoir oil level daily by referring to
the sight gage.
2.
Drain, clean, refill the reservoir and change the
fluid after the first month of operation; every six (6)
months thereafter. Clean the suction strainer and
keep hoses clear. Automatic transmission fluid is
the recommended product.
System Pressure
1.
Hydraulic system pressure is correctly set at the
factory and should not require adjustment for a
considerable period of time. On hydraulic systems,
correct system pressure varies between 200 and 300
psi (13.8 and 20.7 bar or 14.1 and 21.1 kg/cm²).
