DRAINING HYDRAULIC OIL &
CLEANING STRAINER FILTER
Because hydraulic systems operate at over a
thousand PSI and temperatures reaching over
100º F, severe injuries and death can result from
component failures and care must always be
taken when performing maintenance on hydraulic
systems.
WARNING! Hot hydraulic oil burns!
Do NOT drain your hydraulic oil if
you have been using the machine
for longer than 10 minutes!
Step 1: Drive your MAGNATRAC to a level area,
such as a flat garage floor. Make sure no by-
standers are in the area, and that the area is well
ventilated. Raise & lower front attachment for ap-
prox. 3 minutes to get the fluid warm.
Step 2: Shut off the unit, set your parking brake,
and lower all front and rear attachments to the
ground.
Step 3: Rock all hydraulic attachment valve han-
dles, (including backhoe valve handles) back and
forth, approx. 5 times to relax all cylinders. See
picture below. (Backhoe valve NOT shown).

Step 4: Place an oil drain pan, or a clean 5 gallon
pail, (enough to hold approx. 4 gallons), near the
right rear fender, just under the oil drain plug as
shown in the picture on the top of the next column.
Note: You may have to "wedge" the oil pan be-
tween the tracks and the fender, or support it
from the backside to hold it in position.

Step 5: Using an adjustable crescent wrench,
loosen the oil drain plug and allow the fluid to
come into the pan or pail. Note: removing the
breather may allow the fluid to drain quicker. Fol-
low the procedure outlined on the previous page
for removing the breather.
Step 6: Remove seat and rear cover assembly if
it not already removed. See page 23.
Step 7: Once, the fluid is fully drained, remove
the hose clamp from the suction hose. (Inside the
body, driver's right rear). See below.
