1.2 ROUTINE MAINTENANCE
CAUTION: Always disconnect the
power when cleaning, servicing, or
lubricating your drill, see Lock Out Pro-
cedures, page v .
Production losses can be reduced if good maintenance
practices are followed. The following suggestions may
be helpful:
1. Recognize the fact that the user of hydraulic equip-
ment has more control over maintenance than the
manufacturer.
2. Operators should be familiar with use, care, and
limitations of the equipment. ALL OPERATORS
SHOULD READ THIS MANUAL COMPLETELY.
3. Use properly trained maintenance personnel.
4. Establish a program of systematic preventative
care for your equipment or put this machine on an
existing preventative maintenance program.
5. Analyze and isolate trouble before having any part
of the equipment dismantled.
6. Be aware of how your machine should sound and
perform. If the machine is not operating properly or
if it doesn't "sound right", stop running your job im-
mediately and try to identify the problem.
7. Call the dealer for any problems that cannot be
handled by your own personnel.
1.2.1 Daily
1. Sharpen the hollow drills often and reset the spindle
adjusting knobs if needed.
2. Lubricate the hollow drill frequently with the lubri-
cating stick provided.
3. For better hollow drill life, remove the drills when
not in use, clean out, and soak in light oil. Wipe off
excess oil before drilling.
1.2.2 Weekly
(or every 40 hours of operation)
1. Check the drive belt tightness and wear. The drive
belt must be kept tight or it will stall the motor and
plug or break the drills. See Section 1.3.2 for in-
structions on how to tighten the belt.

2. Clean and oil the guide bar shafts around frame.
3. Clean and oil the rear support brackets.
1.2.3 Monthly
1. Check the hydraulic oil supply for the proper level.
This check is made by removing the rear panel and
visually inspecting the level of the oil in the clear
reservoir. The oil should be filled to the fill line on
the tank. If your machine is equipped with a dip
stick on the breather cap, remove the cap and
check the dip stick. There should be approximately
1/8" (3 mm) of oil on the stick.
Use only one of the recommended oils or an ISO
VG 100 Hydraulic Fluid equivalent. Oils other than
the recommended type will cause seals, cups and
O-rings to deteriorate. See Section 1.5.
1.2.4 Yearly
1. Check all adjustments.
2. Tighten all screws.
3. Change hydraulic oil in reservoir. Oil may have to
be changed more often if contamination of any kind
gets in the oil. (Capacity: 1
4. Grease lift springs.
1.3 ADJUSTMENTS
1.3.1 Table Position Adjustment
Set the backgauge to the 1" position. Drill a few sheets
of paper and measure the distance between the cen-
ter of each hole to the edge of the paper. If it is not 1"
(2.5 cm), loosen the (4) screws that mount the table to
the base and carefully move the table to compensate
for the error. Tighten the screws and drill some more
paper. Repeat this procedure until the holes measure
1" (2.5 cm).
