Periodic Inspection
Perform the following steps every week.
1. Test all access cover interlock switches.
Juicer should stop automatically when any access cover is opened. Individually open and
close the front door and hopper access door. If juicer continues to run when front door or
hopper access is opened, the interlock switch is defective.
Stop the juicer and replace the defective interlock switch immediately.
See Troubleshooting Section.
2. Inspect casters for damage or wear.
Caster must roll freely and front and rear brakes must lock.
3. Check all fasteners for tightness.
Check especially on the Sprockets, Crank Arms, Fruit Lift and Hopper.
4. Check chain for tightness.
Refer to Figure 9.
Chain should have 1/4 inch maximum slack on top side. To adjust, loosen the tensioning bolt
located on the chain tensioner until 1/4 inch of slack is measured.
CAUTION: DO NOT OVER TIGHTEN CHAIN.
5. Check chain and sprockets for rust.
Lubricate chain and sprockets should rust appear. JBT Select FG Spray (Non-Drip),
p/n 575054, is recommended.
6. Lubricate grease fittings with JBT Select 2FG grease, p/n 575066.
