When handling hydraulic fluid, use appropriate
measures to prevent spillage. Clean any spillage
immediately.
1) Add Hydraulic Fluid
Add hydraulic fluid as required and check the fluid level
monthly. The reservoir is full when TMA is unfolded
AND when the fluid level is just visible inside the fill
port. Use only Dexron® III Hydraulic fluid. Figure 30
shows the location of the hydraulic fluid fill port.

2) Oil Swivel jacks
Oil the swivel jacks every six months as shown in
Figure 31.

3) Change Hydraulic Fluid
Change the hydraulic fluid every 2 years, 50,000 km
[30,000 miles], or if you strongly suspect the oil is
contaminated with water. Use Dexron® III fluid only.
The empty oil capacity of the reservoir, hoses, and
cylinders is approximately 4 quarts (the capacity of
the reservoir alone is approximately 2 ½ quarts).
The reservoir and hydraulic system may need to be
filled and cycled several times to remove air that may
be in the system.
Caution: When refilling an empty system, do
not attempt to fold or unfold the system more
than 60 degrees until after cavitation has
ceased. Always stay clear of a moving TMA.
As the TMA is folded/unfolded, the pump will cavi-
tate when the reservoir is emptied. Add fluid until
system will raise to 60 degrees without cavitating.
After that, cycle the system beyond 60 degrees and
add fluid as necessary. the reservoir should be full
(oil just visible at the filler port) when the TMA is
fully unfolded. If this procedure is not followed, the
TMA may come down faster than expected (whether
folding or unfolding).
