Automatic Feed Drilling
Attachment
The only maintenance required for
the automatic drill feed gear case
(furnished with the H-603 Electric
Power Operator, or H-604 Air Power
Operator) is the occasional check to
see that it has sufcient lubrication.
The gear case contains one pint
or one pound of SAE 90 gear oil
(multipurpose grease). The oil level
may be checked by removing the
small oil plug located on the side of
the gear case when the gear case
is positioned level with the driving
sockets on the bottom. Oil should be
level with this plug hole. Oil may be
added through the plug located on
top of the gear case.

Bypass Valve
A push-pull type valve is used on
B-101 Machines for bypassing
and relieving pressure. (The valve
is available as a separate part to
replace the ground-key style valve
used on older B-101 and B-100
machines.) The valve is attached to
the machine by two screws and can
be removed easily for cleaning the
valve or machine body passages.
Operation
1. Bypass: push the knurled knob in
all the way against the bypass valve
body.
2. Relief: pull the knob out all the
way until it stops, away from the
valve body.
Maintenance
The spool should be periodically
removed and cleaned.
1. Remove retaining ring.
2. Pull spool out of bypass valve
body.
3. Clean spool and O-rings of old
lubricant and foreign matter.
4. Clean the bore inside the
valve body and examine for deep
scratches that could cause leakage
or abrade the O-rings. Replace the
entire valve and its sealing gasket
if necessary (Gasket is supplied
attached to valve body.)
5. Examine the O-rings for damage
and replace if necessary. Lubricate
the O-rings with a silicone grease.
6. Reassemble the spool and
retaining ring.
NOTE: It is recommended that
a spare Repair Kit (part number
682087) be kept available for
timely repairs.
