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%.
Note, model VW5300 reservoir has a capacity of 10
gal (38 liters).
Dukane suggests DTE
temperature breakdown rating. Refer to Table 11-I for
hydraulic fluids equivalent to DTE
To fill the reservoir, unscrew the filler cap shown in
Figure 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 cylinder 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.
