2. MAINTENANCE:
Adding Oil to the Pump:
Check oil regularly and add oil if
required. Refer to procedure below:
• Place pump in the horizontal
position on a level surface.
•
Remove oil fill plug from reservoir.
•
Check oil level (see figure below).
If oil level is low, add additional oil
until level is touching the bottom
on the thread.
•
Reinstall the oil fil plug into the
reservoir. Ensure the plug is fully
tightened.
• Remove air from the system if
necessary and recheck the oil
level.
IMPORTANT:
• Always add oil with the cylinders
fully retracted (extended with
pull Cylinders) or the pump will
contain more oil than reservoir
capacity.
•
Do not overfill! There must be an
air space in the reservoir to allow
proper operation. If the reservoir
contains too much oil, a vacuum
will form preventing oil from
flowing into the piston of the pump
when operating.
Pump oil should be changed twice
a year. The following conditions
require more frequent oil changes:
• Rigorous duty, where oil may leak
out or become contaminated.
• Highly humid environment and
extreme changes in temperature
that can result in condensation
inside the reservoir.
• Dirty or dusty environments that
may contaminate the oil.
Flushing the Pump:
If you suspect your pump has been
contaminated or discover sludge or
other deposits on internal
components, you should thouroghly
flush the pump.
• Remove the old oil from the
reservoir, then thoroughly clean
and refill with nonflammable
flushing oil.
• Reasemble the pump head to the
reservoir and pump the handle
approx 50 times with the release
screw open.
•
Empty the reservoir and refill
with clean hydarulic oil (BOSS
recommends and uses grade 46
oil).
