Hydraulic Power Service - J&M SpeedTender LC290 Operator's Manual

Removing From Storage
1. Grease the conveyor bearings. Use only two pumps of grease per bearing.
NOTE: Excess lubrication of these bearings will result in premature failure.
NOTE: The conveyor has four bearings that need greased (two at each end). See "Conveyor Service" on page 21.
2. Grease pivot points on boom arm.
3. Ensure wheel lug nuts are properly torqued. See "Bolt Torque Specifications" on page 10.
4. Ensure tires are properly inflated. Tire care guidelines can be found in "Tire Service" on page 19.
5. Check your belt for proper tracking every 10 hours of use and before every season. For steps to properly track your belt see "Adjusting Conveyor
Belt Tracking" on page 23.
NOTE: When checking the belt for tracking you should empty out the conveyor clean out door. See "Cleaning out Collapsible
Hopper and Conveyor" on page 15.
6. Check oil level.
7. Inspect for hydraulic oil leaks and repair as appropriate.
8. Check all hoses, fittings, bolts, and hardware to ensure they are secure and properly tightened.
9. Check engine oil level. See engine operator's manual for details on oil levels, oil types, and service intervals.
10. Check SpeedTender brakes and lights before each time you tow.
11. Ensure the conveyor hopper guard is in place.
12. Reattach battery and check to ensure it is fully charged.
IMPORTANT: Be sure to disconnect the scales from the battery before charging.
Daily (every 5 hours of use):
1. Check oil level.
2. Inspect for oil leaks and repair as necessary.
3. Check all hoses, fittings, bolts and hardware to ensure they are secure and properly tightened.
4. Check motor oil level. See engine operator's manual for details on oil levels, oil types, and service intervals.
Once per season (every 20-25 hours of use):
Change hydraulic oil filter element with either a NAPA 1552 or a FRAM P1654A Filter.
Every two to three years (every 75-80 hours of use):
Drain oil reservoir and refill with clean, good quality hydraulic AW 32 oil. (It is not recommended to refill with tractor hydraulic oil).
Replacing hydraulic parts:
Refer to "Hydraulics Schematic for Aluminum Valve" on page 54 or "Hydraulics Schematic for Black Intercomp Valve" on page 56 for
proper part description and part number for replacement.
Purge air from system as follows:
1. Disconnect the rod end clevis of all cylinders in a circuit and block up cylinders so the rod can completely extend and retract without
contacting any other components.
2. Pressurize the system and maintain system at full pressure for at least 5 seconds after cylinder rods stop moving. Check that all
cylinders have fully extended or retracted.
3. Check hydraulic reservoir and refill as needed.
4. Pressurize system again to reverse the motion of step 2. Maintain pressure on system for at least 5 seconds after cylinder rods stop
moving. Check that cylinders have fully extended or retracted.
5. Check for hydraulic leaks using cardboard or wood.
6. Repeat steps 2, 3, 4 and 5 (3 to 4 times).
7. Depressurize hydraulic system and connect cylinder rod clevises to their mating lugs.
