2. Check hydraulic hoses.
Hydraulic oil under pressure can penetrate body tissue causing serious injury and
possible death. When troubleshooting a hydraulic system for leaks, always use
cardboard or wood as a detector. DO NOT USE YOUR BARE HANDS. If you are
injected with hydraulic oil or any other uids, immediately seek treatment by a doctor
trained in the treatment of penetrating uid injuries.
a. Fully raise the loader arm, install and secure the safety support.
b. Follow all of the hoses, line and tubes from the control valve to their end (Items 1, 8
and 9, Figure 4–6). It will be necessary to remove the service access cover (Item 5,
Figure 4–6). Remove the four bolts and washers (Items 6 and 7, Figure 4–6) and then
the service cover. Inspect the connections and look for signs of leaking hydraulic uid,
wear or damage.
c. Carefully inspect both sets of quick couples (Item 2, Figure 4–6) to make sure that they
are not damaged or leaking.
d. Make sure to check for signs of leakage or damage to the drive motors (Item 4,
Figure 4–6) and to their hydraulic connections.
