Step 11. Connect Hoses - MacDon A30-S Unloading And Assembly Instructions

STEP 11. CONNECT HOSES

IMPORTANT
Hoses should be routed so there are no
twists or sharp bends, and no locations
where contact with the frame is likely.
Ensure that there is sufficient length of
hose and wiring in span to accommodate
full swing of APT in both directions.
Re-locate plastic ties if necessary to
provide suitable slack in hoses and wiring.
IMPORTANT
To prevent contamination of the hydraulic
system, extreme care must be taken to
avoid dirt entering at connection points. To
minimize exposure
remove cap from one hose and its mating
connection, and connect before removing
other caps and plugs.
a. Cut shipping wire holding hoses on the walk
platform, and route to connections at aft end of
APT.
b. Remove wrapping from hose ends. Do not
remove cable ties holding hoses together.
c. Remove caps and plugs from manifold and
hoses.

LOW PRESSURE HOSE
(RETURN)
Ensure that pressure and return hoses are
connected to the proper fitting as shown.
High pressure hose is marked with "4000
psi", and is slightly larger and stiffer than
return hose. Check that it connects to
lower fitting on motor as shown. Tighten
all hoses securely.

e. Connect lift cylinder hose (A) and wiring harness
(B) to the respective fittings on the APT.
f. Check oil level is between ADD and FULL marks
on sight gauge on side of APT. If required, add
oil as follows:
1. Slowly unscrew filler cap (C) from filler tube.
2. Add SAE 15W40 oil until level is between
ADD and FULL marks on sight gauge.
3. Replace filler cap.
