NOTICE
Please read through and understand the entire contents of the operator’s manual prior to using the
implement.
The information in this manual was correct at the date of print. Howard Marshall Engineering Ltd (HME) re-
serve the right to change the specication of products as required without prior notice. Please contact HME if
there are any aspects of the manual that you do not understand.
One operator’s manual is supplied with each attachment to inform the user how it should be operated and main-
tained. It is therefore advised that every operator must read and study the text in this manual thoroughly before
using the implement.
SAFETY
WARNING
Do not stand between the front loader and power unit. Risk of
crushing and jamming. Always lower the loader/attachment
to the ground prior to working on it.
WARNING
Refer to the serial number plate on the attachment for the weight
of your model as it will eect the maximum load capaci-
ty. During use be aware of increased weights due to shock
loading. Shock loading is the result of magnied load weight
from bouncing caused by driving at speed on uneven surfaces
for example. This can cause dangerous overload.
WARNING
Do not allow persons to sit or ride on the attachment at any
time, or perform adjustments unless the machine is stopped,
switched o, and the implement is on the ground.

SAFETY CONTINUED
Only use the attachment with the correct loader/attachment it was designed for. HME do not accept any dam-
ages to bracket as a result of incorrect tting or from the use of adapters or any home-made conversions.
Do not use the implement for any other purpose than for which it was designed for. Please see operating in-
structions, limitations of equipment.
Ensure that the attachment is used within the lift capacity of the loader.
Ensure that the attachment works correctly once it is attached to the loader.
As an operator it is your responsibility to familiarise yourself with the functions to ensure your competence.
Use the appropriate guards / tine and fork covers when driving on public roads.
Remember that driving characteristics of the power unit can be inuenced by the attachment.
Never use the attachment if it has been damaged or is not working properly.
WARNING
Always ensure the working area is clear of persons or live-stock,
take extra care when operating in farmyards or tight spaces.

1. Lower the loader frame to align mounting bars with the receivers;
2. Drive forward until the mounting bars are in the receivers;
3. Raise the loader so the locking pins go through the mounting holes. Continue to raise the loader until the
faces touch but do not lift up the attachment;
4. Turn o the engine, apply the brakes and remove the key;
5. Secure the clevis pins into the locking pins on both sides of the attachment. see gure 2;
6. Ensure the hydraulic connections are clean then connect the hydraulic hoses to the auxiliary hydraulic
hookup on the loader;
Detaching of attachment
Detaching of the equipment shall only be carried out by a single operator.
1. Position the attachment as per storage instructions;
2. Turn o the engine , apply the brakes and remove the key;
3. Disconnect the hydraulic hoses from the auxiliary hydraulic hookup on the loader;
4. Remove the clevis pins from the locking pins on both sides of the attachment;
5. Start the engine and lower the loader to retract the locking pins from the mounting holes;
6. Reverse the power unit until the mounting bars are clear of the receivers.
Pre operation checklist
Before each use, carry out the following checks:
• Check the power unit and loader are in good working order;
• Check hydraulic hose connection;
• Check mounting connection is secure (ensure clevis pins are in place);
• Ensure no one is immediately around the equipment or in the direction of travel. Do not allow riders;
• Check all safety decals are present and legible;
• Ensure an appropriate counter balance is connected to power unit for the intended task;

Position
The attachment should be stored in the position shown in gure 3, with the hydraulic cylinders in their fully
closed position.
Location
The attachment should be placed on a hard and level surface to prevent it sinking or tipping over time. The
attachment should be kept in a cool and dry environment to prolong service life. If it cannot be kept under
a shelter, the unit should be covered to prevent exposure to the elements. Ensure that the attachment is not
accessable to live-stock or anyone who is not suitably qualied to use it.
STORAGE
Handling of materialsHandling of materials
1. Please refer to the loader and power unit user manuals on the operation of equipment controlling the attach-
ment and to identify suitable Personal Protective Equipment (PPE);
2. Before commencing handling, ensure the load will fall centre of the attachment and overhang on both sides
is minimised, where possible. Ensure that the load does not weigh more than the maximum working limit of
the attachment or the loader;
3. Approach the load with the grab open. Once contact is made with the load, close the arms and tilt the attach-
ment back so the load is resting on the lower tines;
4. Before moving the power unit, lower the attachment as low as safely possible to lower the centre of gravity;
5. When moving larger loads that overhang, such as trees, consider having a competent banksman to oversee
the moving of the load to prevent collisions.
Limitations of equipment
The Log Grab is not designed for the following, as such should not be undertaken or risk damage to equipment,
injury or death:
• Excavation work;
• The breaking up of rubble or frozen material;
• The moving of building materials (such as concrete or steel);
• Demolition work;
• The moving of personnel or live-stock;
• Deforestation work, including stump pulling;
• The arms should not be used as a lever to lift or push anything;

MAINTENANCE
Maintenance must be carried out by a suitably qualied person after 200 hours of use or after prolonged
storage. Before any maintenance is carried out ensure the attachment is lowered to ground level so no
works are carried out overhead. Ensure the engine is o, the breaks are engaged and the key is removed.
RECOMMENDED PPE FOR MAINTENANCE WORK
Hydraulics
Please refer to Hydraulic oil safety data sheet and the power units operating manual before commencing any
maintenance.
Inspect the integrity of the hydraulic hoses by searching for any holes, damaged connections or degradation of
the hose. This should be carried out wearing protective eye wear and gloves. Use a piece of wood or card-
board to nd holes instead of using a hand to prevent possible injury.
Spare parts are available for purchase from HME, please see appendix A for parts list.
Hinges
Please refere to grease safety data sheet before commencing any maintenance.
The hinges should be periodically greased as required. This should be carried out wearing protective eyewear
and gloves. Ensure that the grease nipples and the hinges are clear of dirt, sand or dust as these will increase
the wear on the part and reduce service life.
Spare parts are available for purchase from HME, please see appendix A for parts list.
Paintwork
e paintwork should be monitored to identify any large scratches or scrapes which have le large areas of the
bare steel exposed. Dependent on size and location, it may be suitable to protect the steel with a steel zinc
oxide primer as this will extend the service life of the equipment.
If the paintwork has become degraded over years of use, HME oer a refurbishment service to repaint older
products.
FrameworkFramework
Carry out a visual inspect to identify if there are any cracks, large deections, tears or broken parts on the body.
If these are identied the unit should not be used until suitably repaired.
Spare parts are available for purchase from HME, please see appendix A for parts list.
Safety decalsSafety decals
