Stopping in an emergency
In an emergency bringing the blades to a stop requires familiarity with the controls fitted to the tractor.
To stop the blades in an emergency,
use the tractor ‘ENGINE STOP’ control.
NOTE:
The use of the tractor ‘ENGINE
STOP’ control must
only
be done in an emergency. Its use to stop the machine can cause damage. After an
emergency stop of the machine; ensure that the PTO is disengaged before restarting the tractor.

Dangers due to overhead power lines
There are significant dangers involved when worki
ng in the vicinity of Overhead Power Lines (OHPL’s);
DANGER:
All operators must read the following information and be aware of the risks and dangers involved
when working in the vicinity of Overhead Power Lines (OHPL’s).
WARNING!
Fatal electrocution can occur without contacting a power line. Due to the high electrical potential
between the conductors and the ground a flash over can occur from the power line to any conducting
medium within range. Steel mowers are ideal conductors.
Wherever possibl
e the safest option is always to avoid working in areas close to OHPL’s. Where unavoidable, all
operators must perform a risk assessment and implement a safe procedure and system of work, see section 2.4.1
below.
All operators should perform a risk assessment before operating any arm mower within 10m horizontal distance of
any OHPL’s. If you are unsure do not work in the area. Never put yourself or others at risk.
2.4.1
Risk assessment
Before starting to work near OHPL’s you should always assess the risks. The following points should be
observed;
Know
the risks of contacting OHPLs and the risk of flashover.
Always
find out
the maximum reach height for your machine mounted on its tractor, see
‘Machine general
specification in chapter 1 for guidance.
Always
find out
the location and route of all Power Lines within the work area.
Always
find out
the operating voltage of all Power Lines within the work area.
Always
contact
the local Distribution Network Operator (DNO) who will be able to advise you on the
operating voltage, exclusion zones, the minimum safe working distance and any additional precautions
required.
Never
attempt to
operate the machine within an exclusion zone.
Always
work with extreme caution and plan your work ahead
to avoid high risk areas.
If doubt exists
do not work in the area
– never risk the safety of yourself or others

2.4.2
Emergency Action for Accidents Involving Electricity
Never touch an overhead line - even if it has been brought down by machinery or has fallen. Never assume
lines are dead.
When a machine is in contact with an overhead line, electrocution is possible if anyone touches both the
machine and the ground. Stay in the machine and lower any raised parts in contact or drive the machine out
of the lines if you can.
If you need to get out to summon help or because of fire, jump out as far as you can without touching any
wires or the machine keep upright and away.
Get the electricity company to disconnect the supply. Even if the line appears dead, do not touch it -
automatic switching may reconnect.
