Safety instructions

General safety instructions

Read the manual carefully before using the crane.

Familiarize yourself with the functions and usage of the grapple saw.

Be especially careful when connecting and disconnecting the grapple saw to the crane or

machine.

Extreme caution should always be exercised when using the grapple saw.

Make absolutely sure that no one is within a dangerous distance of the working grapple

saw.

The operator must always have a clear oversight of the work area.

Never insert your hand or any other body part into the machine assembly or under hanging

load during work or when the hydraulic system is active (pressurized).

Walking under a hanging load is always forbidden and the operator is not allowed to lift a

load over people in any circumstances.

Do not overload the grapple saw.

Extraordinary caution should be taken when working near electrical lines or other sensitive

areas. Keep the safety distances. Expect risk of unforeseen movements. Any local

guidelines and regulations for working near power lines must always be followed.

When working in cold or especially freezing temperatures, all movements should ﬁrst be

performed carefully to soften seals in the cylinders and valves.

Never let an outside person handle the grapple saw / machine, before you make sure that

this person has understood all operating and safety instructions.

Always shut down the machine for maintenance, service and repairs. Care should always

be taken when servicing, servicing and repairs.

The tilt function is equipped with a shock valve to prevent overloading the cylinders and

other breakage.

The cylinder for the grapple claws is equipped with a load holding valve.

Instructions for safe operation

It is strictly forbidden to be inside of the risk zone of the grapple saw or crane.

Extraordinary caution should be taken when working near electrical lines or other sensitive

areas. Keep the safety distances. Expect risk of unforeseen movements. Any local

guidelines and regulations for working near power lines must always be followed. Var

ytterst försiktig när du kopplar gripsågen till och från kranen eller maskinen.

The operator must always have a clear oversight of the work area.

Never insert your hand or any other body part into the machine assembly or under hanging

load during work or when the hydraulic system is active (pressurized).

Walking under a hanging load is always forbidden and the operator is not allowed to lift a

load over people in any circumstances.

Localize any problem before any mending attempts, this will prevent unnecessary work and

possibly worsening the situation.

The grapple saws hydraulic hoses and pipes must always be kept in good condition.

Replace any of these immediately when any weakening is detected, especially the ones

connected to the grapple claws. Inspections are to be done daily. Air in the hydraulic

system can cause unforeseen movements, so always “bleed” the system by driving the

cylinder end-to-end several times after replacing any part of the hydraulic circuit.

Use original parts, by using original parts will ensure a more problem free use of the

product. Also note that if a failure is a result of not using original parts, the user assumes all

risk.

Never let an outside person handle the grapple saw / machine, before you make sure that

this person has understood all operating and safety instructions.

Always use appropriate safety gear, like helmet, safety goggles etc.

The cylinder for the grapple claws is equipped with a load holding valve."

Leave the holding valve installed, when the grapple saw will be used for taking down

trees in pieces. (knuckle boom cranes, truck cranes, tele-handlers or similar)."

The valve prevents the the grapple from opening (and dropping the load) in case of a hose

break."

Uninstall the valve, if the grapple saw will be used to fell whole trees that will be cut at

ground level. (Forestry harvesters, forwarders, excavators or similar).

Description of labels / Warning labels

Labels and warning symbols on the grapple

Warning for risk of crushing

Be aware of the risk of being crushed by the

grapple arms, tilt function and other moving

parts on the grapple. Negligence may lead to

severe or fatal injuries.

Warning for the saw

Be aware of the risk of the saw.

The machine must always be turned off before

doing any maintenance, service or repairs on

the grapple saw. Negligence may lead to

severe or fatal injuries.

Other labels that also relate to the use of the grapple

saw

Risk zone 50 m (50 yards).!

The grapple saw also inherits all

possible warnings that applies to the

machine and/or crane it’s installed on

Eg. bigger risk zone.

Make sue you always have a clear view of the

working area. Negligence may lead to severe or

fatal injuries.

Usage of safety gear

Always use appropriate safety gear to avoid

injuries during your work.

Installation

Recommendations and tips

There are some recommendations and tips to consider when installing the grapple saw.

The grapple saw can perform slightly different depending on the machine which it is mounted on.

Both the SG220 and SG280 grapple saw work very well on trucks with long cranes. The SG220

and SG280 with radio control are popular, because no power cable needs be installed along the

crane boom. Only 2 hydraulic lines are needed (grapple open & Grapple close)

Page of 10 50

www.mecanilproducts.com

www.mecanil.ﬁ

NOTE! Load holding valve on the grapple cylinder:!

Leave the valve installed, when the grapple saw is installed on a machine meant for

taking down a tree in smaller pieces. (Mobile cranes, tele handlers, knuckle boom

cranes or similar)

Uninstall the valve, if the grapple saw will be used to fell whole trees that will be

cut at ground level. (Forestry harvesters, forwarders, excavators or similar).

The machine must always be shut down when servicein or doing maintenance

work on the grapple saw!

SG220 and SG280 are to be mounted free hanging, with a rotator and link.

Fixed mounting is not allowed.

We recommend a minimum of ½” hydraulic lines along the boom. !

If quick connectors are used for the hydraulic lines, use one size bigger connectors in "

comparison to the hose size."

NOTE! No bleed line (from saw motor) needed..

If the hydraulic hoses are too small the saw will feel slow and counter (back) pressure will rise. "

The counter pressure should not exceed 50 bar (725 PSIs).

SG220 and SG280 can be installed on a variety; !

Trucks, forwarders, excavators etc.

These recommendations should be noted especially when installing the grapple saw on

a crane with a long boom. For example on a crane with a reach of 20-35 m (60 -120 ft), eg.

knuckle boom cranes, telehandlers or similar.

When installing on shorter cranes smal smaller lines will probably sufﬁce.

The recommended oil ﬂow for SG220 is approx. 50-80 l/min. (13 - 20 gpm).!

The recommended oil ﬂow for SG280 is approx. 60-100 l/min. (15-26 gpm).!

The grapple saw will also work with less oil ﬂow (eg. 40l/min.[10gpm]), but the saw will

then work slower.
