Owner Service 15; Blocking Method - Woods BATWING BW20.50QE Operator's Manual

The information in this section is written for operators who possess basic
mechanical skills. If you need help, your dealer has trained service technicians
available. For your protection, read and follow the safety information in this
manual.
WARNING WARNING
■
Keep all persons away from operator control area while performing
adjustments, service, or maintenance.
■
Before working underneath, disconnect driveline from tractor, lower
wings to the ground, raise cutter, and engage transport lock-up in the
locked position. Attach parking jack and lower to the ground. Securely
block all four corners of the centre section and each wing with jack-
stands. Blocking up prevents the cutter from dropping due to hydraulic
leak down, hydraulic system failure, or mechanical component failure.
■
Service and maintenance work not covered in OWNER SERVICE
must be done by a qualified dealership. Special skills, tools, and safety
procedures may be required. Failure to follow these instructions can
result in serious injury or death.
■
Before servicing, adjusting, repairing or unplugging, stop tractor
engine, place all controls in neutral, set park brake, remove ignition key,
and wait for all moving parts to stop.
■
Never perform service, cleaning, or maintenance with engine run-
ning.
CAUTION CAUTION
■
If you do not understand any part of this manual and need assis-
tance, see your dealer.
■
Always wear relatively tight and belted clothing to avoid entangle-
ment in moving parts. Wear sturdy, rough-soled work shoes and protec-
tive equipment for eyes, hair, hands, hearing, and head; and respirator or
filter mask where appropriate.

BLOCKING METHOD

To minimize the potential hazards of working underneath the cutter, follow
these procedures:
WARNING WARNING
■
Before performing any service or maintenance, lower equipment to
ground or block securely, turn off engine, remove key, and disconnect
driveline from tractor PTO.
■
Never go underneath equipment (lowered to the ground or raised)
unless it is properly blocked and secured. Never place any part of the
body underneath equipment or between moveable parts even when the
engine has been turned off. Hydraulic system leak down, hydraulic sys-
tem failures, mechanical failures, or movement of control levers can
cause equipment to drop or rotate unexpectedly and cause severe injury
or death. Follow Operator's Manual instructions for working underneath
and blocking requirements or have work done by a qualified dealer.
Do not position jackstands under wheels, axles, or wheel supports. Compo-
nents can rotate and cause cutter to fall.
1. Jackstands with a load rating of 453.6 kg (1000 lbs.) or more are the only
approved blocking device for this cutter. Install jackstands (shown by Xs
in Figure 6) under the cutter before working underneath unit.
2. Consider the overall stability of the blocked unit. Just placing jackstands
underneath will not ensure your safety.
The working surface must be level and solid to support the weight on the
jackstands. Make sure jackstands are stable, both top and bottom. Make
sure cutter is approximately level.
3. With full cutter weight lowered onto jackstands, test blocking stability
before working underneath.
4. If cutter is attached to tractor when blocking, set the brakes, remove key,
and block cutter before working underneath.
5. Securely block rear tractor wheels, in front and behind. Tighten tractor
lower 3-point arm anti-sway mechanism to prevent side-to-side
movement.
