HEIGHT ADJUSTER MAINTENANCE
There are a total of eight different height adjuster manuals. See your specific installation instructions sent
with the unit for further information. This is intended as a general information guide only.
CAUTION
MANUAL HEIGHT ADJUSTERS ONLY
i
Do not continue to crank unit once it reaches the 10'-0" or 8'-0" goal heights as this will place undue
strain on the mechanism and possibly jam unit in place.
i
When using a power drill (with the optional No. XCRK 90000 202 Power Drill Adapter) to raise and lower
the height adjuster, use ONLY a battery-operated power drill with a torque (clutch) adjustment. CAU-
TION - As a safety precaution, use the lowest torque clutch setting possible to operate the height adjust-
er, to avoid undue stress on the unit as it reaches the maximum Up (10') or Down (8') positions.
ALL HEIGHT ADJUSTERS (MANUAL AND ELECTRIC)
i
When height adjustment unit is mounted on a folding type backboard support system, always adjust the
goal height to 10'-0" before hoisting or folding the unit so as not to place undue strain on the hoist sys-
tem or the height adjustment mechanism.
i
Always keep the operating device (Hand Crank, Keys from Key Switch, Powr-Stick, Sportsonicâ II
Transmitter, or Powr-Touch Pad) in the possession of a responsible adult trained in the proper use of
this system.
WARNING
Before attempting any repairs, lower the unit to the lowest position (8'-0" goal height) to eliminate the possi-
bility of the backboard dropping suddenly, which could result in serious injuries or death.
CARE AND MAINTENANCE
MANUAL HEIGHT ADJUSTERS ONLY
i
Semi-annually lubricate the entire threaded rod assembly and upper thrust roller bearing with any high
quality multi-purpose type grease.
ALL HEIGHT ADJUSTERS (MANUAL AND ELECTRIC)
i
Periodically inspect height adjustment and support system for loose or defective parts - tighten or re-
place immediately as required.
i
Periodically (at least annually, depending on usage) lubricate the two plated inside slide tubes with a
WD-40 type lubricant. Run height adjuster up and down (10' to 8') several times, and wipe slide tubes
dry to clean any dust or residue build-up. Spray the two plated inside slide tubes once again with a high
quality silicon spray. NOTE - protect the floor with a drop cloth to prevent a slippery build-up on the
gymnasium floor.
