Page: 11 / 31

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 wear items 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.
3.4 Aerator Head/Tine Maintenance
The Aerator tine head is removable. Simply disconnect the 3 ball swivel mounts and pins
(you may want to prop the front of the Aerator head for easy disconnect and re-
attachment. Other attachments such as the Slice Seeder, De-thatch Rake, Spray System
and Snow Plow use the same points). Disconnect the Ball Swivel Assembly Pull Pin
connected to the cylinder bracket (bottom side) and head will be free from unit. Either
pull the Aerator tine head away from unit or slowly turn the unit either left or right
swinging the front of the Z-Plug in a circle motion (this will swing the front of the unit
away from the tine head allowing the operator to drive unit around and away from tine
head or other attachments).
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
3.5 Attachment Maintenance
<Z-Plug Sprayer Attachment: The Z-Plug unit has the ability to mount a 30 gallon
spray system to the frame. Just like our Z-Spray liquid systems, maintenance is a key
requirement to allow successful applications. Here are a few things to maintain on this
system.
Check 5 psi check ball screens daily.
Check spray system in-line filter daily (make sure rubber seal remains intact).
Check spray tips daily for any clogging of materials or foreign objects.
Clean out tank on daily basis for proper storing.
