5. HYDRAULIC CONNECTIONS
The recommended hose length is 25 ft/8 m with a 1/2
inch/12.7 mm inside diameter. The hoses must have a
working pressure rating of at least 2500 psi/175 bar. Each
hose end must have male thread ends compatible with
H.T.M.A. (HYDRAULIC TOOL MANUFACTURERS AS-
SOCIATION) quick disconnect fittings (NPT type threads).
(See Page 8.)
Figure 1. Panel Control Valve
Facing the panel control valve, the bottom male quick
disconnect fitting is the PRESSURE FLUID OUT fitting. The
top female quick disconnect fitting is the RETURN FLUID
IN fitting.
QUICK DISCONNECT COUPLERS
H.T.M.A. approved quick disconnect couplings are installed
to hydraulic hoses so that the direction of oil flow is always
from the male to the female quick disconnect as shown
on page 8. Quick disconnect couplings and hose fittings
are selected so that additional fittings such as reducer or
adapter fittings are not required.
If adapter fittings are used, they must be approved steel
hydraulic fittings meeting a minimum operating pressure
rating of 2500 psi/172 bar. Do not use galvanized pipe fit
-
tings or black pipe fittings.
Use thread tape or pipe joint compound when installing
quick disconnect couplings to hose or tool fittings. Follow
the instructions furnished with the selected thread sealant.
DO NOT OVERTIGHTEN THE FITTINGS.
PREPARATION FOR USE
Do not operate the power unit until you have read the
engine
operating and maintenance instructions manual
furnished with the unit.
1. ENGINE CRANKCASE OIL LEVEL
Always check the oil level before starting the engine. Make
sure the oil level is at the FULL MARK on the dipstick. Do
not overfill. Use detergent oil classified "For Service SE, SF,
SG" as specified in the engine operating and maintenance
manual. See engine manual for oil viscosity grade.
2. SPARK PLUG
On power units equipped with Briggs & Stratton Engines,
ONLY Champion RC12YC or equivalent can be used.
Incorrect type spark plugs can produce radio frequency
interference that will corrupt and damage the controller.
Failure to use the correct spark plug could result in a war-
ranty that will not be considered.
3. ENGINE FUEL LEVEL
Check the fuel
level. If low, fill with un-leaded gasoline with
a minimum of 85 octane.
