6.8 ATTACHMENTS ___________________________________________________________
The Groom Master will accept several attachments
designed to perform a variety of operations. Before
installing and using attachments read and save the
instructionsheetincluded with it.
Contact your Jacobsen Distributor for a complete list of
attachments and accessories available for your machine.
6.9 TOWING / TRAILERING _____________________________________________________
If the unit experiences problems and removed from the
area, itshould be loaded onto a trailer for transport.Ifatrailer
is not available, the unit can be towed slowly short
distances.
Use care when loading and unloading unit. Fasten unit to
trailer to prevent it from rolling or shifting during transport.
Before towing, open tow valve. The tow valve permits
moving the unit without starting the engine and prevents
possible damage to hydraulic components.
The tow valve (A) is located on the hydraulic drive pump
under rear hood. To open valve, insert a pin into the small
hole in the valve stem. Turn the valve counterclockwise one
fullturn.
Before towing make sure attachments are raised. If they
cannotberaised,removethemfromtheunit.

6.11 DAILY MAINTENANCE______________________________________________________
Important: For more detailed maintenance information,
adjustments, and maintenance/lubrication charts, see the
Parts & Maintenance manual.
1. Park the unit on a flat, level surface. Fully lower the
attachments to the ground, engage parking brake, stop
the engine, and remove key from ignitionswitch.
2. Grease and lubricate all points if required. To prevent
fires,washtheunitafter each use.
a. Useonlyfreshwaterforcleaning your equipment.
Note: Use of salt water or effluent water has been
known to encourage rust and corrosion of metal parts
resulting in premature deterioration or failure.
Damage of this nature is not covered by the factory
warranty.
b. Do not use high pressure spray.
c. Do not spray water directly at the instrument panel,
or any electrical components.
d. Do not spray water into the cooling air intake or the
engineairintake.
Note: Do not wash a hot or running engine. Use
compressed air to clean the engine and radiator fins.
e. Clean the tires thoroughly. Check tire pressure.
f. Clean radiator and oil cooler passages using
compressedair(30 psi(2BAR)maximum).
3. Fill unit’s fuel tank at the end of each operating day to
within1in.,(25mm)below the filler neck.
Diesel Engine - Use clean, fresh, #2 low or ultra low
sulfurdieselfuel.MinimumCetane Rating 45.
Gasoline Engine - Use clean, fresh, unleaded
gasoline, 85 octane minimum.
4. Handle fuel with care - it is highly flammable. Use an
approved container, the spout must fit inside the fuel
filler neck. Avoid using cans and funnels to transfer
fuel.
a. Never remove the fuel cap from the fuel tank, or add
fuel,whentheengineisrunning,or whiletheengine
is hot.
b. Do not smoke when handling fuel. Never fill or drain
the tank indoors.
c. Never overfill or allow the tank to become empty.
Donotspillfuel.Cleanany spilled fuel immediately.
d. Never handle or store fuel containers near an open
flame or any device that may create sparks and
ignitethefuelor fuel vapors.
5. Store fuel according to local, state, or federal
ordinances and recommendations from your fuel
supplier.
6. Inspect hydraulic hoses and tubes daily. Look for wet
hoses or oil spots and replace worn or damaged hoses
andtubesbeforeoperatingthemachine.
7. After engine has cooled, check coolant level. Radiator
should be full and recovery bottle should be up to the cold
mark.
8. Park machine in designated area. Engage parking
brake and remove key. Do not part equipment near an
open flame or spark which could ignite fuel or fuel vapors.
Place key in a secure location to prevent unauthorized
useofequipment.
9. Check the engine oil and hydraulic oil at the start and
end of each day. If the oil level is low, remove the oil filler
cap, and add oil as required.Donotoverfill.
WARNING
To prevent serious injury from hot, high pressure oil,
never use your hands to check for oil leaks, use paper or
cardboard.
Hydraulic fluid escaping under pressure can have
sufficient force to penetrate skin. If fluid is injected into
the skin, it must be surgically removed within a few hours
by a doctor familiar with this form of injury or gangrene
mayresult.
WARNING
To prevent serious bodily injury from hot coolant or
steam blow-out, never attempt to remove the radiator
cap while the engine is running. Stop the engine and wait
until it is cool. Even then, use extreme care when
removingthecap.
CAUTION
Do not pour cold water into a hot radiator. Do not operate
engine without a proper coolant mixture. Install cap and
tightensecurely.
