OPERATION MANUAL
Spindle Brake Lever: Quickly stops the spindle
after power to spindle is turned OFF.
High/Low Range Lever: Selects between
low (65 RPM–270 RPM) and high (590 RPM–
2330 RPM) spindle speed ranges.
Belt Tension Adjustment Lever: Adjusts the
V-belt tension by moving the position of the
motor.
Motor Lock Screw: Locks motor position to
secure belt tension.
Belt Safety Cover: Must be secured closed to
protect user from entanglement during opera-
tion. Used for access to V-belt when changing
spindle speed.
Spindle Speed Range Selector: Used in con-
junction with high/low range lever. Engages
back gear for low (65–270 RPM), and disengag-
es back gear for high (590–2330 RPM) spindle
speed ranges.
NOTE: When engaged, the back gear reverses
the spindle rotation, causing the spindle switch
settings to be reversed when in low range
Manual/Power Downfeed Selector: Selects
between manual and power downfeed.
Coarse Downfeed Lever: Quickly moves the
quill downward manually and automatically
retracts spindle to top position when released.
Typically used for drilling operations
Quill Lock Lever: Locks the quill in any position
for best rigidity
Adjustable Downfeed Stop: Limits depth of
the quill travel. The dial is graduated in incre-
ments of 0.01mm. Typically used for repeat
operations.
Fine/Auto Downfeed Clutch Lever: Engages
ne/auto-downfeed gears.
Fine Downfeed Handwheel: Manually controls
slow spindle downfeed for ne Z-axis control.
Auto-Downfeed Direction Pin: Starts, stops,
and reverses the auto-downfeed direction.
Auto-Downfeed Rate Selector: Selects one of
the three auto-downfeed rates:
0.04 mm/rev
0.08 mm/rev
0.15 mm/rev
NOTE:
The correct feed selection depends on the type
of material and the number of cutting edges
on the tool. Refer to the Fitting and Machining
manual (Hafco Code L341)
The following descriptions are explanations of the items for the belt driven head listed in Fig.2.
These will help the operator to become familiar with the basic controls and components of this
machine. Understanding these items and how they work will help the operator understand the
rest of the manual and stay safe when operating this machine.

OPERATION MANUAL
Spindle Brake Lever: Quickly stops the spindle
after the power to spindle is turned OFF.
High/Low Range Lever: Selects between
low (50 RPM–400 RPM) and high (400 RPM–
3550 RPM) spindle speed ranges.
Spindle Speed Range Selector: Used in con-
junction with high/low range lever. Engages
back gear for low (50–400 RPM), and disengag-
es back gear for high (400–3550 RPM) spindle
speed ranges.
Note: When the back gears are engaged, the
spindle rotation, is reversed and the switch set-
tings need also to be reversed in low range
Digital Variable-Speed Display: Displays the
spindle speed when the machine is in both the
high and low range.
Spindle Speed Range Selector: Engages
back gears for low (50 RPM–400 RPM), and
disengages back gears for high (400 RPM–
3550 RPM) spindle speed ranges.
NOTE: When engaged, the back gears reverse
the spindle rotation, causing spindle switch
settings to be reversed when in low range
