Exmark Lazer ZXS manual Adjustments

4.1.18Thread locking adhesives Fel-ProPro-Lock"Nut-Type" or Loctite Threadlocker "242" are used on the following:

a)All belt drive pulley setscrews.

b)OPC lever setscrews.

c)Pulley retaining bolt in end of engine crankshaft.

d)Fuel tank bulkhead fitting threads.

Adhesives such as Loctite "RC/609" or "RC/680" or Fel-ProPro-Lock "Retaining" or "Retaining II" are used on the following:

a) OPC lever hubs and cross-shaft.

NOTE: When applying any locking adhesives, care must be used not to bond the bearing (next to each OPC hub) to the cross-shaft. This could cause binding of the OPC levers and erratic operation.

b)Fuel tank studs, where studs are inserted into tank.

4.1.19An anti-seize compound is used on the following locations:

a)Between the blade drive and transmission drive pulleys and engine crankshaft.

b)Between the transmission drive pulley and transmission drive shaft.

c)Between the bearings and sheaves and transmission output shafts.

4.1.20Mobil HTS grease (or food-grade antisieze) is used in the following locations:

a)Between the cutter housing spindle and bearings.

b)Between the cutter housing spindle and sheave.

4.1.21Dielectric grease is used on all blade type electrical connections to prevent corrosion and loss of contact.

4.2ADJUSTMENTS

4.2.1Adjusting cutting height with blade spacers.

Blades may be adjusted for cutting height by using the four 1/4" (.64 cm) spacers found on the blade spindle bolts (factory setting is two above and two below). This allows a 1" (2.5 cm) range in 1/4" (.64 cm) increments of cutting height in any axle position. The same number of blade spacers must be used on all blades to achieve a level cut (two above and two below, one above and three below, etc.).

For the best cut and discharge, place a minimum of two spacers between the blade and spindle shaft.

For the highest quality cut, place all four spacers between the blade and the spindle shaft.

If the mulching kit is installed, the highest quality cut can be obtained with 3 spacers between the blade and spindle (minimum is 1 for a good cut).

If you need to cut higher or lower than what the spacers will allow, it will be necessary to adjust the rear axle height and caster position. See Section 4.2.2 below.

4.2.2Axle height and caster position.

Desired cutting height range can be obtained by adjusting the rear axle and placing caster spacers above or below the caster arm (See Figures 10 and 11 along with the Cutting Height Adjustment Chart). It may be necessary to readjust wheel drive and brake linkages.

To adjust rear axle:

a)Stop engine and wait for all moving parts to stop. Remove key or spark plug wire(s).

b)Place the drive levers in the neutral lock position.

c)Remove mower deck belt shield for access to axle adjustment bolts.
