SERVICE TIP

BEFORE DOING ANY SERVICE OR MAINTENANCE ON ANY MACHINE, FOLLOW ALL LOCKOUT PROCEDURES. THIS SHOULD INCLUDE:

1. DISCONNECT THE ELECTRICAL POWER SUPPLY.
2. RELIEVE THE PRESSURE FROM THE HYDRAULIC SYSTEM (CHECK THE PRESSURE GAUGE ON THE POWER UNIT TO MAKE SURE IT READS ZERO).
3. MECHANICALLY SECURE ANY PART OF THE MACHINE THAT MAY SHIFT WHILE DOING MAINTENANCE.
   

GENERAL

• Check all fasteners for tightness and tighten as required (refer to maintenance checklist below).

• Check for hydraulic motor and fluid leaks and repair immediately.

• When disconnecting and reconnecting hydraulic lines, make sure the o-ring seal is in its proper seat. These can become unseated during the re-assembly process resulting in hydraulic leaks.

• Check fasteners for tightness.
• Check that bearings are adequately greased.
• Check the bar to be sure it rolls freely. Put the bar at the point to where it is about to roll under the wear plate. The bar must turn freely. (A general check for this while it is running is when the bar rolls off the block, at this point it will turn backwards. If it does not turn backward, it may chip the back block.)
• The bar not rolling freely is a sign of premature bar and pin wear.
• Check for hydraulic motor and fluid leaks. Repair if necessary.
• Check the chain tension. (See Figure 1)
