Caution: When changing glass thickness, back off the front arris spindle, #2, and slowly dial
in the amount of arris to be ground. This should match the rear arris grind, which should not
have to be changed when glass thickness changes.
Maintenance
(1). Check the electrical ground connection to guarantee safe operation before working everyday.
(2). After working everyday, sweep away broken glass pieces and glass grind from the water tank
then wash it and check the coolant pipeline for blockage. Clean the machine, use light oil on
exposed or unpainted areas. Lubricate the slide plate of the spindles and front conveyor with light
machine oil.
(3). Use special step-less reducer lubrication oil (Mobil SHC 630 Synthetic) to lubricate the
mechanical step-less reducer. Change this oil every 1,000 operating hours. The oil level should
show on the oil gauge to avoid high oil temperature. Add grease to lubricate bearings and gears of
the step-less reducer every 3,000 operating hours. Use Mobil #350 oil in the worm gear box and
change it every 1,000 operating hour. Oil level should be at the middle of the oil gauge or have the
box
½
full.
(4). Grease the bearings, gears and sprockets of the right and left gearbox every 3 or 4 months of
operating.
(5). Change the water in the coolant tank periodically. Too much glass powder will block the
pipeline and pump, and affect the grinding quality, shortening wheel life.
(6). The machine is equipped with a Central Lubrication System for the pad slideway. It is located
on the lower right front corner of the machine base. Fill this reservoir with 10 wt. light oil and, after
the plastic lines have filled with oil, pump the handle 5-8 times slowly while the machine is running.
This will keep the pad slideway lubricated. Be sure to get oil onto the entire length of the conveyor
as it passes the oil tube. Perform this task every 2 weeks and vary the oiling as needed due to high
production or less use. The chain links will benefit from having grease applied to them with a small
brush. Remove the guards and operate the conveyor slowly while carefully brushing grease on the
links as they pass along the chain sprocket on the end on the conveyor.
(7). Check the front and rear conveyor pads periodically, when most of the conveyor pads have
worn seriously, all should be changed.
(8). Check the wearable plates of the slideway periodically; change them when most of them have
worn seriously.
