Site Preparation
Refer to Figure 2
1. Clear obstructions and hazards at the work sites on
the drill.
Note: Some hydraulic hoses can be protected with tarps,
do not obstruct access, and may be left in place.
Some cannot be left in place during welding, and
must be disconnected. If the drill is equipped with
hydraulic down pressure, several hoses on the
right side of the drill need to be removed.
Note: Hose disconnection will result in some spillage of
hydraulic fluid, and the welding to be performed
will create a shower of sparks. Perform hose clear-
ing at a different location than used for welding.
Note: It may also be necessary to remove the forward
walkboard, if present, on the left side of the drill.
2. Connect a suitable tractor, raise the drill and install
lift cylinder locks.
3. Set each hydraulic circuit to Float to relieve pres-
sure, then disconnect each at the hitch. Leave the
tractor hitched to the drill.
!
CAUTION
Some pressure may remain in hoses controlled by valves on the
drill.
4. Mark each side of a hose disconnection point to
assure correct re-connection later. Disconnect each
hose at a JIC or NPT fitting (and not at an O-ring
boss fitting). If available, cap or plug open lines.
Move the disconnected hoses out of the work area,
and tie them to frame parts, away from tires.
5. Engage existing pivot locks. Move the drill to a loca-
tion suitable for welding. Make sure the ground or
floor under the drill is non-flammable.
6. There will be sparks from welding. Dry grass, wood
floor, or areas with flammable fluid spills are not suit-
able locations for installing this upgrade.
7. Before coming to a complete stop, pull drill straight
forward with tractor and lower hitch slightly to relieve
pressure on existing pivot locks. Raise pivot locks.
8. Block drill transport tires to prevent movement. Dis-
connect hydraulic and electrical lines to tractor.
Unhitch tractor.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury.
▲ Slowly open fittings before disconnecting hydraulic lines.
▲ Wear protective gloves and safety glasses or goggles when
working with hydraulic systems.
▲ If an accident occurs, see a doctor immediately. Any fluid
injected into the skin must be surgically removed within a
few hours or gangrene may result.
