6.4 Spring platform Adjustment
The factory setting is both springs set at the most forward position. The more rearward the spring position, the
stiffer the platform gets. Adjustment will be to preference of feel. The two adjustment springs should at all
times, be positioned next to each other not one forward or back more than the other. To adjust, loosen each
spring retaining bolt from the top just enough to slide it, then tighten with impact wrench. The nut may spin
using hand wrench. NOTE, do not loosen too much, if the nut falls off, the foot platform will have to be
removed to reinstall. There is an extra hole for a third spring for operators heavy enough to bottom out the
duel spring stock set up.
6.5 Hydraulic System
Whenever servicing the hydraulic system, it is of the utmost importance to keep any dirt or debris from getting
into the system. Clean off all parts before disassembly and assembly. When any of the hydraulic parts are
disconnected or removed or when the oil is changed, air must be bled from the system. If air is entrained in
the system, loss of power, excessive heat, and damage to the hydraulic pumps may occur.
