Important Safety Information
Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is a potential
hazard to personal safety involved and extra safety precaution
must be taken. When you see this symbol, be alert and
carefully read the message that follows it. In addition to design
and configuration of equipment, hazard control and accident
prevention are dependent upon the awareness, concern,
prudence and proper training of personnel involved in the
operation, transport, maintenance and storage of equipment.
Be Aware of Signal Words
Signal words designate a degree or level of hazard seriousness.
DANGER indicates an imminently hazardous situation which,
if not avoided, will result in death or serious injury. This signal
word is limited to the most extreme situations, typically for
machine components that, for functional purposes, cannot be
guarded.
WARNING indicates a potentially hazardous situation which,
if not avoided, could result in death or serious injury, and
includes hazards that are exposed when guards are removed. It
may also be used to alert against unsafe practices.
CAUTION indicates a potentially hazardous situation which,
if not avoided, may result in minor or moderate injury. It may
also be used to alert against unsafe practices.
Prepare for Emergencies
Be prepared if a fire starts
Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone.
Be Familiar with Safety Decals
Read and understand “Safety Decals” on page 5,
thoroughly.
Read all instructions noted on the decals.
Keep decals clean. Replace damaged, faded and illegible
decals.
Wear Protective Equipment
Wear protective clothing and equipment.
Wear clothing and equipment appropriate for the job.
Avoid loose-fitting clothing.
Because prolonged exposure to loud noise can cause
hearing impairment or hearing loss, wear suitable
hearing protection such as earmuffs or earplugs.
Because operating equipment safely requires your full
attention, avoid wearing entertainment headphones while
operating machinery.

Preparation and Setup
This section helps you prepare your tractor and VT1510 Sub-
Soiler for use, and covers tasks that need to be done
seasonally, or when the tractor/Sub-Soiler configuration
changes.
Before using the Sub-Soiler in the field, you must hitch it to a
suitable tractor, inspect systems and level the Sub-Soiler.
Before using the Sub-Soiler for the first time, and periodically
thereafter, certain adjustments and calibrations are required.
Prior to Going to the Field Checklist
Complete this checklist before routine setup:
Read and understand “Important Safety Information”
on page 1.
Check that all working parts are moving freely, bolts are
tight, and cotter pins are spread.
Make sure your tractor horsepower matches the
implement you are pulling. This is important so the
implement can do the best possible job.
Clean all hydraulic couplings and connect to tractor as
shown on page 13.
Check again for hydraulic leaks and watch that hoses do
not get pinched in hinges, wing stops, etc.
 Check that all grease fittings are in place and lubricated.
See “Lubrication” on page 23. The hubs will come pre-
greased and will not need greased at this time.
Check that all safety decals and reflectors are correctly
located and legible. Replace if damaged. See “Safety
Decals” on page 5.
Inflate tires to pressure recommended and tighten wheel
bolts as specified. See “Torque Values Chart” on
