  Lubrication 

 

Do not operate the mill before 

lubricating the machine fully. Failure to 
comply may cause damage to the machine. 

 
Refer to 

section 11.0

 and make sure the machine 

has been fully lubricated before operating.

  Operating instructions 

9.1

  Operating controls 

The milling machine is equipped with an automatic 
lubrication system.  Ensure that reservoir has the 
proper amount of lubricant.  The system reservoir is 
located at rear of machine. 

The position of the mill head can be set up to 
accommodate the workpiece being machined. The 
mill head can be set up for angles to left or right and 
for fore and aft angles. The mill head can also be 
rotated on its turret. The ram can be moved back 
and forth to reach workpiece locations at fore and 
aft extremes of worktable travel. Refer to 

section 

10.0.

 

9.2

  Control panel 

The control panel is located on the arm at right side 
of machine. See Figure 4 for functions.

A

 

– 

RPM digital readout.

 

B – 

Motor direction switch:

 Has two positions: 

FWD (forward) and REV (reverse). Setting the 
switch to FWD will provide clockwise spindle 
rotation. Use FWD for normal, right-hand tooling.  

FWD (clockwise) operation occurs only when 
gearbox is in low speed position. When gearbox is 
in high-speed position, the motor switch must be in 
the REV position to provide right-hand or clockwise 
rotation. Refer to Table 2 for required switch 
positions. 

The motor switch controls a three-phase motor. The 
motor can be switched from FWD to REV and back 
with the motor running, and will reverse direction 
when the switch setting is changed. At higher 
speeds, this may put strain on the timing belt but 
there will be no damage to the motor or gear 
mechanism. 

C – 

Coolant switch

: installed for optional coolant 

pump. The wiring must be connected to U2, V2 and 
W2 in the terminal strip. 

D – 

Power lamp

: indicates electrical power is 

flowing to machine. 

E – 

Speed dial

: Sets spindle speed. 

F – 

Spindle switch

: Engages spindle rotation. 

G – 

Emergency stop switch

: Shuts down all 

controls on machine. Rotate switch clockwise to 
disengage and restart machine.
