pivot grease fitting. Grease boom pivot

monthly. Do Not Over Grease. There is a

Pop-Out Valve above the grease fitting, if

the pin pops out enough grease has been

applied. Wipe off excess grease. Excess

grease will attract dirt.

• The boom pivot is equipped with a hardened

shaft and Timken roller bearings. If the

boom becomes loose, you will need to apply

pressure to the bearings to tighten it. To

apply more pressure to the bearings, hold the

bottom nut where the cotter pin is. Remove

the top nut and tighten the second nut, which

will apply pressure to the roller bearings and

the boom swing. You can place cutter

wheel on ground and put slight pressure on

cutter wheel to adjust pivot bearings.

If for some reason you need to replace the main pivot bearings, you will have to remove the top

pin and slide the main pivot out and install the new bearings.

• Boom must be placed in a fixture to hold steady when you remove the pivot pin. (SEE
