Changing The Oil; Cleaning The Muffler - Enerpac PTA-1404 Bedienungsanleitung

3. Insert new overlay (remember
to verify correct overlay to the
Enerpac torque wrench being
used) onto the flange, aligning
the overlay with the dimples on
the back of the flange (see Fig.
8).
4. While holding the
behind the flange (see Fig. 7.)
insert the flange onto the knob
studs, repositioning
overlay as needed,
secure knobs finger tight (see
Fig. 6).
The flange will press the
overlay onto the gauge and
secure it in place. See torque
wrench instructions for amount
of pressure required to produce
desired torque. Note that the
maximum pressure varies for
different wrenches
accessories.
CAUTION: Refer to torque
wrench instructions
wrench operating procedure.
4.4 Pressure (Torque)
Adjustment
WARNING: Make these
adjustments
putting torque wrench
on nut or bolt head. The pump
pressure setting may be above
the pressure needed to provide
the required torque for your
application. Exceeding required
torque will cause equipment damage and may lead to serious
personal injury.
REFER TO TORQUE WRENCH INSTRUCTIONS FOR
WRENCH OPERATING PROCEDURE.
1. Loosen locknut and back out relief valve (F) to prevent
unintended pressure build-up. (See Figure 9.)

2. Press and hold the "Advance" pushbutton and read pressure
gauge.
3. While holding the "Advance" pushbutton, turn relief valve in
(clockwise) to increase pressure or out (counter-clockwise) to
decrease maximum pressure. Repeat until correct pressure
is obtained. NOTE: THE "ADVANCE" button must be released
and then repressed to verify pressure when decreasing
pressure setting.
4. Tighten locknut on relief valve to maintain setting.
5. Run the pump several times to test the pressure setting.
NOTE: Perform Air Removal and Pressure (Torque) Adjustment:
1. during initial operation or start-up
2. when connecting a different wrench to the pump
3. when changing torque value (pressure adjustment only).
5.0 MAINTENANCE

5.1 Changing the Oil

Completely drain the reservoir after every 250 hours of operation.
If pump is operated in very dusty areas or at high temperatures,
drain and refill more frequently.
1. Remove the breather cap from reservoir.
2. Tip the pump until all old oil has drained out.
3. Add new hydraulic oil through breather opening until the oil
level is one inch below the vent/fill opening. Reservoir
capacity is 1 gal. [3,7 L].
4. Replace the breather cap.
5. DISPOSE OF USED OIL PROPERLY.

5.2 Cleaning the Muffler

When the pump is run for long periods of time, ice may form on the
muffler element and must be removed.
unscrew the front plate and remove any debris.
5.3 Cleaning the Air-Filter Lubricator
Inspect the air-filter lubricator frequently to detect crazing,
cracking, or damage. Replace damaged bowls.
Keep the filter bowl clean to maintain filtering efficiency. Turn drain
valve (G) clockwise from bottom to drain any bowl accumulation.
(See Figure 10.)
G
A visible coating of dirt or condensate on the filter element or an
excessive air pressure drop indicates that cleaning is necessary.
Depressurize the unit before removing bowl for cleaning.
