2. Actuate and hold left propel function over relief.
Engine pulldown must not go below 1950 rpm. If
it does, turn rear pump load adjusting cartridge
(I) out until pulldown is 1950--1970 rpm. Record
rpm reading. Release propel function.
3. The pulldown rpm reading for front and rear
pumps must be within 10 rpm of each other to
prevent machine from mistracking.
4. Check combined pump pulldown by operating
the arm in function through several cycles. The
combined pump pulldown must be less than 150
rpm. If more than 150 rpm, turn both load
