MAINTENANCE
HYDRAULIC OIL
WARNING!
To avoid hydraulic oil injection or injury, always wear appropriate clothing and eye protection when working with or near hydraulic
system.
Check the Hydraulic Oil Level. Unlatch and swing open the Oil Reservoir / Fuel tank Cover (20) . Remove the reservoir cap to check
the oil level. The hydraulic oil level should be half way up the screen filter inside the filler neck of the reservoir. Add SAE 10W30 motor oil
if it is below this level. Change the oil if major contamination from a mechanical failure occurs.
Change the Hydraulic “Charge” Oil Filter once a year or every 1000 hours.
HOPPER DUST CONTROL FILTER (PANEL FILTER)
The hopper dust control filter must be cleaned regularly to maintain the efficiency of the vacuum system. Follow the recommended filter service
intervals for the longest filter life.
CAUTION!
Wear safety glasses when cleaning the filter.
Do not puncture the paper filter.
Clean the filter in a well-ventilated area.
Wear appropriate dust mask to avoid breathing in dust.
To remove the hopper dust control filter...
1 Unlatch and open the Hopper Cover (16) . Make sure that the Hopper Cover Prop Rod (17) is in place.
2 Inspect the top of the Hopper Dust Control Filter (12) for damage. A large amount of dust on top of the filter is usually caused by a hole in the
filter or a damaged filter gasket.
3 Unthread and remove the four Shaker Assembly Retainer Knobs (13) . Lift off the Dust Filter Shaker Assembly (11) to access the panel filter.
4 Lift the Hopper Dust Control Filter (12) out of the machine.
5 Clean the filter using one of the methods below:
Method “A”
Vacuum loose dust from the filter. Then gently tap the filter against a flat surface (with the dirty side down) to remove loose dust and dirt.
Method “B”
Vacuum loose dust from the filter. Then blow compressed air (maximum pressure 100 psi) into the clean side of the filter (in the opposite
direction of the airflow).
Method “C”
Vacuum loose dust from the filter. Then soak the filter in warm water for 15 minutes, then rinse it under a gentle stream of water (maximum
pressure 40 psi). Let the filter dry completely before putting it back into the machine.
6 Follow the instructions in reverse order to install the filter. If the gasket on the filter is torn or missing, it must be replaced. NOTE: Before
replacing filter clear debris from dust plate located under filter. Verify that the debris flap at the rear of the dust plate swings freely
HOPPER DUST CONTROL FILTER (OPTIONAL NILFISK POCKET FILTER SYSTEM)
The optional Nilfisk pocket filter system is basically maintenance free. The only periodic maintenance required by the machine operator is to run the
Shaker (LL) on a daily basis. NOTE: The shaker should only be run with the hopper in the down position.
