GEARBOX LUBRICATION (H14A WITH A412 GEARBOX)
The Bonglioli A412 gearbox used on the H14A is supplied with 5.0 litres (1.32 US gallon) of Mobil SHC 630 synthetic oil.
This oil has an ISO Viscosity Grade of 220 that is optimum for ambient temperatures from 10 – 40 Deg C [70 – 104 Deg
F]. If the machine will be operated for prolonged periods at ambient temperatures below 20 Deg C [70 Deg F] an oil of
ISO Viscosity Grade 150 should be substituted.
The suggested oil change interval is given below:
Oil Temperature
Deg C [Deg F]
Mineral Oil Interval
[hours]
Synthetic Oil Interval
[hours]
< 65 [< 150] 8000 25000
65 – 80 [150 – 175] 4000 15000
80 – 95 [175 – 200] 2000 12500
NOTE: Oil ll and breather, level gauge, and drain points appear on drive wheel tracking illustration shown previously.
TROUBLE SHOOTING GUIDE
Most problems that occur have one of the relatively simple solutions that appear in this section. If the solution is not
found here, contact the HYD MECH distributor from whom you purchased your bandsaw. They have trained eld service
personnel who will be able to rectify the problem.
NOTES:
1. IF THE BLADE IS RUNNING CLOCKWISE OR THE HYDRAULIC PUMP IS NOISY, SHUT THE SAW DOWN
IMMEDIATELY!
2. IF THE DRIVE MOTOR IS TO BE REPLACED, IT MUST BE REPLACED WITH A TOTALLY ENCLOSED,
FAN COOLED (TEFC) MOTOR TO PREVENT COOLANT LEAKING INTO THE MOTOR.
3. THE HEAD SHOULD BE LOWERED FULLY, OR ONTO SUITABLE SUPPORTS, BEFORE ANY HYDRAULIC
SERVICE IS PERFORMED, TO PREVENT THE HEAD FROM MOVING UNEXPECTEDLY.
