Travel Setting Rod
– Periodically insert SAE
20W oil into the ball oiler on each end of the
rod (Figure 9).
15.
Tailstock
– Daily lubricate two ball oilers
(Figure 15) on top of tailstock with SAE 20W
oil.
The anti-dust felt beneath the tailstock that
runs along the ways should be cleaned weekly
with kerosene. If the felts become damaged,
replace them.

V-Belts
– Regularly check and adjust the
tightness of the v-belts to prolong their service
life. See
section 13.5

Coolant Preparation
Follow local regulations and/or
coolant manufacturer’s recommend-dations for
use, care and disposal.
1.
GH-2680ZH:
Remove access cover on the
tailstock end of the lathe stand. Make sure
coolant pump has not shifted during transport.
Pour four gallons (approximate) of coolant mix
into the reservoir.
GH-26120ZH:
Pour coolant (approx. four
gallons) into one of the chip trays (Figure 16).
Or, slide out one of the chip trays and pour
directly into the side trough on the center
stand.
2. After machine has been connected to power,
turn on coolant pump and check to see that
coolant is cycling properly. Flow is controlled
by the tap at the base of the nozzle.
3. Reinstall access cover or chip tray.

Electrical Connections
Electrical connections must be
made by a qualified electrician in compliance
with all relevant codes. This machine must be
properly grounded while in use to help protect
the operator from electrical shock and possible
fatal injury.
The main motor is rated for 230/460V and comes
from the factory prewired at 230V. Confirm that
power available at the lathe’s location is the same
rating as the lathe.
A minimum 10-gauge wire should be used for
incoming power leads.
IMPORTANT:
The lathe must be wired properly
and phased correctly.
The spindle must rotate
counterclockwise
(as viewed from the tailstock
end) while the
feed rod must rotate clockwise
(as
viewed from the tailstock end). If the motor runs
and the lathe operates, but the
rapid traverse does
not function
, this signals that the machine has been
incorrectly phased. If this occurs, disconnect lathe
from power source and switch any two of the three
power leads (not the green ground wire).
Main Power Switch
(Figure 17).
Power Source Cable Receiver
(Figure 17).
Make sure the lathe is properly grounded.
