**USE COMPRESSED AIR (NOT WATER)
WHEN CLEANING HYDRAULIC SYSTEM**
Hydro-Gear recommends that the fluid and filter(s)
be changed after the first 100 hours and every 500
hours thereafter. Use Exmark Premium Hydro Oil
when replacing the oil in your system. The hydraulic
reservoir should be filled so the oil level is half way
up the sight window.
Hydraulic system requires 25 micron oil filters or
equivalent to be used.
Check for hydraulic leaks daily to ensure proper fluid
levels.
Traction Unit Maintenance
The machine has 11 grease fittings that require
periodic greasing. These locations can be found
on the wheel assembly (1 on each front wheel
assembly), on the caster assembly (1 on each front
caster assembly), and the drive belt idler (1 on idler
arm), Pillow Block Bearings (4 each) and 2 on the
Lift Cylinder..
Inspect wheel and caster assembly every 25 hours for
bearing wear, damage, debris, and proper installation.
Inspect idler arm bushing every 50 hours for wear.
These bushings are a wear item and will have to be
replaced periodically.
Inspect all bolts, washers, nuts, pins and other
mounting hardware of Z-Plug once a week to ensure
that hardware pieces are properly tightened.
Spreader Maintenance
The Z-Plug comes equipped with a 120 lb spreader
and requires the same amount of attention and
maintenance.
**USE COMPRESSED AIR (NOT WATER)
WHEN CLEANING HOPPER**
Lubricate (Silicone Spray) Hopper, Deflector and
Diffuser cables weekly.
Clean debris and product from Hopper daily to
eliminate build up.
Keep hydraulic hose fittings tight and free of leaks.
Be sure that the Rate Gate & Diffuser Guides are not
damaged to allow the hopper door to slide freely.
Check agitator wire on a daily basis. If wire is not
present, product will run the risk of building up prior
to reaching hopper door and not spreading evenly.
Aerator Head/Tine
Maintenance
Check all tines to ensure that there is no bends,
cracks and/or damages to the tines (replace any bent,
cracked and/or damaged tines).
Check to make sure that all nuts on tine head
assembly are tight and secure.
Check to ensure that pillow block bearing assembly is
secured and bearings are moving freely.
