HOPPER DUST CONTROL FILTER
The hopper dust control fi lter must be cleaned regularly to maintain the effi ciency of the vacuum system. Follow the recommended fi lter
service intervals for the longest fi lter life.
CAUTION!
Wear safety glasses when cleaning the fi lter.
Do not puncture the paper fi lter.
Clean the fi lter in a well-ventilated area.
To remove the hopper dust control fi lter...
1
Lift the Hopper Cover (16) on top of the hopper. Make sure that the Hopper Cover Prop Rod (9) is in place.
2
Inspect the top of the Hopper Dust Control Filter (17) for damage. A large amount of dust on top of the fi lter is usually caused by a hole
in the fi lter or a damaged fi lter gasket.
3
Turn the two hold-downs to the side (one on each side at the front of the frame) to release the shaker frame, then swing the Dust Filter
Shaker Assembly (18) up and latch in place with the Shaker Assembly Latch (19).
4
Lift the Hopper Dust Control Filter (17) out of the machine.
5
Clean the fi lter using one of the methods below:
Method "A"
Vacuum loose dust from the fi lter. Then gently tap the fi lter against a fl at surface (with the dirty side down) to remove loose dust and
dirt. NOTE: Take care not to damage the metal lip which extends past the gasket.
Method "B"
Vacuum loose dust from the fi lter. Then blow compressed air (maximum pressure 100 psi) into the clean side of the fi lter (in the opposite
direction of the airfl ow).
Method "C"
Vacuum loose dust from the fi lter. Then soak the fi lter in warm water for 15 minutes, and then rinse it under a gentle stream of water
(maximum pressure 40 psi). Let the fi lter dry completely before putting it back into the machine.
6
Follow the instructions in reverse order to install the fi lter. If the gasket on the fi lter is torn or missing, it must be replaced.
HYDRAULIC OIL
Raise and prop (HH) the hopper. See Figure 8. The oil level should be approximately 1 inch (2.54cm) below the bottom of the Elbow (A) on
the front of the reservoir when the hopper is up (when the hopper is fully down the oil level should be up to the bottom of the elbow). If it is
below this level, add 10W30 motor oil. Change the oil if major contamination from a mechanical failure occurs. SERVICE NOTE: The Plug
(B) on Elbow (A) on the side of the reservoir is for adding oil. Service Note: Remove Vent Plug (D) to allow faster fi lling.
IMPORTANT!
This machine is equipped with an Indicator Light (F) which lights if the Hydraulic Oil Filter (C / Figure 8) requires changing. The
Hydraulic Filter (C / Figure 8) is found on the side of the Hydraulic Power Unit (27) as shown.
