CARE, CLEANING & MAINTENANCE
LUBRICATION (once per season, or as required):
1. Elevation Control
Apply fresh grease.
2. Horizontal Swivel Lock
a. Completely remove the horizontal swivel lock. Clean all old grease, dirt, etc. from
the threads.
b. Wipe the threads with a very small amount of fresh grease.
c. Reinstall.
THROWING WHEEL MOTORS
Motors are sealed and require no lubrication.
Check bolts for tightness once a season. Tighten bolts securely, but do not over-tighten.
See Figures 9 and 10 on page 11.
CLEANING THE THROWING WHEELS
The throwing wheels must be kept clean to maintain accuracy. Clean the wheels periodically
to control the build-up of grass and dirt.
1. Turn the on/off switch “OFF” and allow the wheels to come to a complete stop. Unplug
Junior Hack Attack from electric power.
Dampen a rag with soap and water. Turn the throwing wheel by hand and scrub the wheel
until the build-up is removed. For very heavy build-up, a synthetic scouring pad, such as a
Scotch-Brite
®
scouring pad, or medium sandpaper may be used sparingly. Methyl Ethyl
Ketone (M.E.K.) may be required to help loosen the build-up of dirt or ball residue.
EXAMINE THE MACHINE
Examine Junior Hack Attack for condition and completeness before every use:
1. For batting practice, be sure the horizontal swivel lock is secured.
2. Throwing wheels must be tight on the motor shafts. Check that the keyway retaining
bolts are tight.
3. Wheel guard and ball chute must be securely fastened to the throwing head.
