While rotating the vacuum head assembly in the counterclockwise position, make
sure that it spins freely all the way down. If it begins to require the slightest finger
tip pressure, unscrew it and brush off the threads. All it takes is the slightest grain
of dirt or sand to obstruct the threads. If you turn too far onto a grain of dirt, the
hub may become locked onto the shaft of the gear box.
PERIODIC MAINTENANCE
Oil Level
Check the oil level in the gear box on a monthly basis.
This is a permanently lubricated gear box. You do not need to change the oil. However,
maintaining the proper oil level is important.
1. To check the oil level, remove the vent plug and look into the gear box.
2. Turn the cleaning head until you can see the inspection hole in the gear.
3.
With the PowerHead sitting flat on a table or the floor, the oil level should be up to,
but not above, the middle of the gear.
4. If oil needs to be added, use a quality 80-90 weight gear oil.
When checking the oil level in the gear box, use a toothpick as a dip stick. The oil
level should read 3/8” deep.
