Adding Hydraulic Fluid - Dukane VWA-4300 User Manual

Adding Hydraulic Fluid

The vibration welder may be shipped with the hydraulic
fluid reservoir full or completely drained, depending on
whether the destination is local or international. Before
operating the welder, hydraulic fluid must be added to
the reservoir if it is low or empty. The reservoir has
a capacity of 20 U.S. gallons (75.7 liters). Normal
operating level is about 18.5 gallons (70 liters). This
corresponds to a sight glass reading of 50%.
®
We prefer DTE 25 because it has a higher temperature
breakdown rating. Refer to Table 11-I for hydraulic fluids
®
equivalent to DTE 25.
To fill the reservoir, unscrew the filler cap shown in Fig-
ure 3-11. Pull out the strainer/filter. Add hydraulic fluid
until the sight glass level gauge reads 50% as shown in
Figure 3-12. There will still be fluid in the hydraulic cyl-
inder so it is not necessary to completely fill the reservoir.
Replace the strainer/filter and screw the filler cap back
on. After the table has been cycled a few times, recheck
the fluid level. It may be necessary to add more hydraulic
fluid if the sight glass level has dropped below 50%.

Hydraulic fluid level should be
maintained so that it always
shows in the fluid level sight
glass. This is important to
prevent condensation from
collecting on the inside of the reservoir and
the heat exchanger tubes.
