1. Check the oil level in the gearbox on a monthly
basis. This is a permanent lubricated gearbox. You
do not need to change the oil. However, maintain
ing the proper oil level is important. To check the
oil level, remove the vent plug and look into the
gearbox. Turn the “star” until you can see the
inspection hole in the gear. With the unit sitting
flat, the oil level should be up to, but not over, the
middle of the gear. If oil needs to be added, use a
quality 80-90 weight gear oil.
HELPFUL HINT: When checking the oil level in the gearbox, use a toothpick as
a dipstick. The oil level should read
3
/
8
".
2. Remove and rinse the filter screen from the flow control valve.
3. Change the felt seal. This is recommended after every ten hours
of use. (For step by step instructions on removing the cleaning
head and the seal, please refer to the “REPAIR GUIDE”
section.) Always keep a spare felt seal soaking in 30 weight
oil. By immersing the felt in oil, it will expand like a sponge and providE
sufficient seal for a good vacuum. Place the worn seal back in the oil bath
to rejuvenate.
HELPFUL HINT: An ideal container in which to soak the spare felt seal
is a commercial tuna can. It is the right size and shape and does not
require a large amount of oil.
After placing the refreshed, oil-soaked felt seal in the hub, coat the
surface with 30 weight gear oil. Lightly oil the inner hub threads
before reattaching the cleaning head to the machine.
