The harvester head usually processes trees with the
front at the operator’s right and the rear at left, to allow
better visual control of the main saw cut. Trees are thus
fed from the operator’s right to left.
Consider the front from a seated position in the
operator's seat, with the harvester head directly in front
of you and the harvester head arms as being left and
right.

Safety: General Precautions
1-2-2

Operator Protective Structures
XJ1298962—UN—22JUN20
Machines with harvesting or felling heads should be
tted with an operator protective structure (OPS): bars
and so on to prevent operator injury from penetrating
objects such as trunks and branches. The cab front
window should also be strong enough (e.g. double
safety glass) to prevent chain shot injuries. The carrier
should have a roll-over protective structure (ROPS) to
prevent the operator being crushed should the machine
roll over.
The machine operator, supervisor, or owner must
always check the cab of the carrier to ensure the cab is
equipped with OPS and the OPS is not visibly damaged
when working in the woods. He must also check and
comply with the local and regional requirements for
operator protection for forestry harvesting or felling
operations. See
ISO 8082 Forestry – Operator
Protective Structures (OPS) for internationally
recognised performance requirements. Some regions
have additional requirements beyond ISO 8082.
IMPORTANT: The harvester head must be operated
in a manner that prevents debris from hitting
the cab.
T7M7G6M,00004D6-19-28JUL21
Inspect the Harvester Head
T6607AQ—UN—15APR13
Before starting each day, walk around the harvester
head and carefully inspect it. Look for signs of damage,
unusual wear, or fatigue cracks. Pay special attention to
exposed parts such as the cylinder rods or hoses.
Note all safety devices on the harvester head and
ensure they are working properly. Make sure all guards
and shields are in good condition and properly installed.
Replace missing or damaged warning and caution
labels.
CAUTION: Modifying, moving, or removing
safety devices tted to the equipment could
result in injury or death.
Make sure the harvester head adjustments are correct
and the delimb arms and saw chain are sharp. Inspect
the saw chain and saw bar condition for excessive wear
or damage daily, and also immediately after hitting a
rock or other foreign material.
Inspect all hydraulic hoses. Check the hydraulic oil
regularly and add oil when required.
IMPORTANT: Fix any damaged parts, and replace
worn or broken parts, immediately. Note faulty
operation when it occurs, and follow up with a
service check.

Service Safety
Ensure that the tilt frame is in the harvesting or
processing position, and that the locking pin is installed
to lock it there. By default, the locking pin is kept in the
carrier’s tool box. The locking pin insertion locations are
shown in the service manual for the harvester head.
Always make sure the attachment is securely
supported. Do not support the machine on cinder
blocks, hollow tiles, or props that may crumble under
continuous load.
If it is necessary to work on a raised boom or harvester
head, ensure they are supported and secured to
prevent the boom from lowering, or the harvester head
from moving. Do not work under a suspended harvester
head, or one supported solely by a jack. Doing so could
result in injury or death.
TS229—UN—23AUG88
XJ1298952—UN—22JUN20
Always turn off the harvester head prior to commencing
service. Working between the delimb arms, between the
feed arms, or in the cutting path of the saws while the
hydraulic system is active could result in injury or death.
Always remain on the ground or on a safe platform to
carry out repairs or maintenance. Standing on
equipment is a safety hazard, and could result in injury
or death.
Always use proper lifting procedures when moving
product components. Heavy parts may require
mechanical hoists.

Hydraulic Repair Safety
T133509—UN—15APR13
This machine uses a high-pressure hydraulic system.
Possible hazards include:
●Residual pressure could cause sudden movement of
the head, which could result in injuries.
●Working in the “pinch” or “saw” area of the harvester
head while the hydraulic system is active could result
in injury or death.
●Escaping oil under pressure can easily penetrate the
skin, resulting in serious injury.
●Hydraulic oil becomes hot during operation, and if it
comes into contact with the skin, may cause severe
burns.
Avoid the hazards by turning off hydraulic systems
before maintenance or service work is performed.
Always reduce the hydraulic system pressure to zero,
relieving pressure before disconnecting hydraulic lines
or starting to work on any hydraulic component.
Remember to re-tighten all connections before re-
applying pressure.
Under Pressure
If it is necessary to work on the hydraulic system while it
is under pressure (for example, searching for leaks),
always wear gloves, approved eye protection, and full
protective clothing.
T133840—UN—20SEP00
Never search for leaks with your hands: Use a piece
of cardboard to nd the location of escaping oil by
holding it over the suspected leak.
Warning: If hydraulic oil penetrates your skin, see a
doctor immediately. Injected oil must be removed
surgically within hours or gangrene may result
T7M7G6M,00004EA-19-02APR21
Welding Repairs Safety
IMPORTANT: Disable carrier and harvester head
electrical power before welding. Separate
harness connectors from the engine and
vehicle microprocessors.
T133547—UN—15APR13
Avoid welding or heating near pressurised uid lines.
Flammable spray may eject and cause severe burns if
pressurised lines fail as a result of heating. Do not let
heat extend beyond the work area.
TS220—UN—15APR13
Hazardous fumes can be generated when paint is
heated by welding. Remove paint properly. Do not
inhale paint dust or fumes. Do not use a chlorinated
solvent in areas where welding will take place.
●Remove paint to a minimum of 100 mm (4") from the
area affected by heating. If paint cannot be removed,
use an approved respirator before heating and/or
welding.
●Wear an approved respirator if you sand or grind
paint, to avoid breathing the dust.
●If you use solvent or paint stripper, remove the
stripper with soap and water before welding. Remove
solvent or paint stripper containers and other
ammable material from the area. Allow fumes to
disperse at least 15 minutes before welding or
heating.
Ensure there is good ventilation, and wear eye

3 — Saw bar tip
4 — Saw chain drive sprocket
5 — Saw chain catcher
6 — Chain shot guard
The function of the chain shot guard (6) is to reduce the
risk of serious injury or death to operators and
bystanders from ying saw chain pieces. The chain shot
guard must be in place and structurally sound to absorb
the energy from a broken saw chain (1) and reduce the
whip action that causes a second break of the saw
chain, ejecting pieces of the cutting saw chain at high
speed. For additional information about chain shot, refer
to Avoid Chain Shot in the safety section of this manual.
Inspect the chain shot guard daily or when saw chain
maintenance is performed.
Saw chain breaks are the primary cause of wear or
damage to the chain shot guard.
The chain shot guard, cap screws, and hardware should
be replaced yearly or when excessively worn or
damaged.
Safety: Maintenance Precautions
1-3-7

Identication of excessive chain shot guard wear
and damage:
●Inspect for wear or damage of the chain shot guard,

●Inspect for wear on each end of the chain shot guard.
●Inspect for possible cracking on any portion of the
chain shot guard.
●Inspect for perforations or holes anywhere on the
saw chain shot guard.
●Make sure that the chain shot guard is not worn thin
and still maintains the original shape and prole.
●Inspect for possible metal peeling or tearing back
over any portion of the chain shot guard.
Replace the chain shot guard if any of these
condition are present:
●The guard does not maintain its original shape.

General Operation Precautions
Check with local authorities regarding local safety
regulations.
Starting
When starting an operation in a new location, determine
a work zone.
Choose an agreed working procedure among the team
working with the harvester head, and do not change it
without further discussion.
Before each period of operation, test to ensure that all
safety equipment, instruments, and controls are working
correctly.
Operation – General
During operation, keep all windows and doors closed.
Always wear a safety belt in case of unexpected carrier
movement.
When working at night, ensure the work area has
adequate lighting. Use a recognised safety light with a
bulb protected by a wire cage.
Always lower the harvester head and its load to the
ground when taking a break. Leaving a load suspended
could result in the head or stem falling, causing injury or
death.
Do not pass a load over another vehicle, even if it
appears empty. It could cause injury to someone out of
the operator’s line of sight.
Raise the harvester head before moving the vehicle.
When traveling, keep it high enough to clear stumps or
other objects.
When moving a log from or to a stack, keep movement
smooth. Sudden moves and abrupt stops could damage
the harvester head, or be a potential source of injury
from dislodged material.
Operation – Work Zone
Make sure no one stands in the cutting direction of the
saw chain. The chain shot hazard zone is approximately
15 degrees towards the rear of the sprocket and in front
of the bar tip.
Keep all personnel 90 metres (300 feet) away from the
harvester head during tree felling.
Ensure the work zone is clear before felling a tree or
processing a stem. Safely stop the harvester head
immediately if someone enters the zone.
Operation – Clearance
Keep a safety clearance of at least 5 metres (16 feet)
between power lines and the nearest point of contact of
the harvester head.
When working in a restricted area, check for
interference with cylinder rods, hydraulic hoses,
electrical cables, etc.
Always allow enough distance between the stem and
the harvester cab.
Finishing
Always park the carrier so the harvester head is on level
ground before turning the engine off and exiting the
operator’s cab. If the engine shuts down without the
harvester head in the parking position, restart the
engine and position the head on the ground in a
stabilised position.
IMPORTANT: The harvester head can fall
unpredictably when the engine is shut down. If
the engine cannot be restarted, lower the
harvester head to the ground and release any
held stem before exiting the cab.
Do not exit the cab and approach the harvester head
until the head is lowered to ground and trapped
hydraulic pressure has been released.
T7M7G6M,00004EB-19-28JUL21
Avoid Work Site Hazards
XJ1298959—UN—22JUN20
Prepare the work site properly. Avoid operating near
structures or objects that could fall onto the machine.
Clear away debris that could move unexpectedly if run
over.
Avoid contact with overhead electrical lines. To
avoid hoist (boom) or attachment contact with overhead
electrical lines, never move the machine closer than 3
metres (10 feet) plus twice the line insulator length to
overhead wires.
Keep bystanders clear at all times. Use barricades or
a signal person to keep vehicles and pedestrians away.
Use a signal person if moving the machine in congested
areas, or where visibility is restricted. Always keep the
signal person in view and use radios or hand signals to
maintain communications.
Operate only on solid footing with sufcient strength
to support the machine. Be especially alert working near
embankments or excavations.
