5.0 Installation Guide

Note: Further adjustments may be necessary once the machine is ready to drill. See Table Position
Adjustment (See section 9.2.1 on page 25).
5.3 Installing the Drill Blocks and Drills
Always handle drills with care to avoid severe lacerations. Even dull drills
are sharp enough to cause lacerations.
Place the drill block knock-outs in position (refer to Figure 1 if necessary). Now set the three drill
blocks place. Check to see if the blocks are flush with the table. Place shims under the blocks if
necessary.
Insert the tapered head of the hollow drills into the spindles. Be sure that the drift hole covers are in
place before operating the machine (Figure 1). The drift hole covers prevent paper chips from flying
out while drilling.
5.4 Hydraulic Level Check
Check the level of the oil in the hydraulic reservoir. This check is made by first removing the louvered
panel at the left side of the stand (two screws hold it in place) and locating the breather cap on the top
of the reservoir. The breather cap has a dip stick attached for checking the oil. When screwed in
(and then removed to check) there should be approximately an 1/8” (3 mm) of oil on the stick. Some
machines are equipped with a clear reservoir in which case the oil level can be checked by visually
inspecting the oil level. There is a full level line marked on the reservoir. Recommended oils are
found in the maintenance section of this manual (page 23).
5.5 Hooking up the Power Line
Always disconnect the power when cleaning, servicing, or lubricating your
drill, see Lock Out Procedures, page 4.
This EH-3D is factory wired for 230 Volts, single phase, 50/60Hz and is supplied with a power cord
with a NEMA ‘L6-30P’ plug. It is the customer’s responsibility to have a NEMA ‘L6-30R’ receptacle
wired by a licensed electrician to a 30 Amp circuit (minimum). If your location requires this machine to
run on 208 Volts, a qualified technician should open the power panel cover and move the jumper that
is located in the terminal block from 11 and 11A to 11 and 11B. Replace the power panel cover
before plugging the machine into the wall socket.
IMPORTANT: Select the proper voltage link to match the voltage supplied to the machine
(Figure 6).
