Drill press operator pulls power feed
engagement lever into disengaged
(toward right) position.
To set depth of cut for power feeding:
Refer to Figure 14.
1. Unlock both levers (A, Figure 14).
2. Rotate feed levers (B) to lower drill until it
touches workpiece.
3. Rotate dial (C) until required feed depth on
scale is at zero reference mark (D).
4. Lock both levers (A).
5. Push power feed engagement lever (F) toward
the left.
6. Pull feed levers (B) out to engage power feed
clutch. The power feed mechanism will feed
drill into workpiece at the rate selected on feed
rate dial, until selected depth of cut is
complete.
Note:
The depth limit for power feed drilling is
4.0 inches (100mm). If deeper holes are
needed, the machining must be done in steps.
IMPORTANT:
Feed rate must be set (out of neutral
position) before power feed can be engaged.

Spindle direction and power
feed
Spindle rotation direction is managed by the
arm/spindle control lever on left side of drill head.
See Figure 15.
Figure 15: Spindle/arm control lever
Clockwise or "forward" rotation is the direction of
rotation for right-hand tooling – the vast majority of
tooling used in machine operations. Reverse
spindle rotation for left hand tooling.
Power feed direction is determined by the spindle
direction. When spindle is set to its most common
direction – clockwise or forward – the quill and
spindle are driven downward. When spindle
direction is set counterclockwise (reverse), quill
and spindle are driven upward.
8.14
Hand feed – roughing
operations
When the feed levers are pushed toward the drill
head the power feed mechanism is disengaged. In
this position, the feed levers can be used to move
the quill and spindle and perform manual drilling or
other machining operations.
8.15
Fine hand feed using power
feed system
The fine feed handwheel is located on underside of
front of drill head. See Figure 10. The fine feed
control is used as follows:
1. Set feed rate lever to far right to disengage.
2. Pull feed levers out to engage power feed
clutch.
3. Turn drill press power switch to ON, and set
arm/spindle control lever to desired direction.
4. Manually turn fine feed handwheel. Quill and
spindle will move downward or upward
(depending upon which way you turn
handwheel and the direction spindle is turning)
until you stop turning the handwheel.
8.16
Tapping
1. Insert screw tap into spindle.
2. Move spindle into position.
3. Set spindle control to Forward.
4. Rotate feed levers counterclockwise until
desired tapping depth is reached.
5. Reverse spindle direction and allow tap to
withdraw completely from workpiece.
6. Stop spindle by moving spindle control switch
to center (neutral).

Power ON/OFF
If your J-1600R was connected to its service
branch correctly, there will be a service disconnect
with an external power cutoff lever or switch which
disconnects the drill press from the service branch.
This is your ultimate protection against accidental
machine start-up when clamping work pieces or
inserting and removing tooling. Always be certain
