load beyond rated capacity.
!
WARNING
• Never extend leg extensions beyond
factory marked position on each
leg.
• Extend each leg extension an equal
distance from frame.
• Never fold crane with safety hook at-
tached to a load.
• Store folded crane with boom exten-
sion fully retracted.
• Move crane slowly and ONLY over
smooth, level surfaces.
• Failure to heed these markings may
result in personal injury and/or
property damage.
OPERATION
1. Ensure application is compatible with
product.
2. Secure engine to chain/sling hook
assembly, ensuring load is centered.
3. Follow vehicle service manual
recommendations to remove engine.
When ready to remove engine, turn
release valve clockwise until firm.
Pump handle until load is high
enough to clear vehicle.
4. Immediately upon removal and when
clear of the vehicle, lower the load to
the lowest practical position by
turning the release valve lever
counter-clockwise slowly and
carefully.
Note
: Avoid rolling the loaded engine
crane. To help position an engine stand
if necesary, move only across smooth,
level, seamless surfaces.
Before
moving ensure the load:
a. is lowered to the lowest practical
position, but always below the center
of gravity.
b. is prevented from swinging and
inadvertent shifting.
5. Position a suitable engine stand near
the removed engine, then immedi-
ately transfer the load to appropriate
engine support device (engine
stand). Check to ensure stand is
secure before working on or around
the load.
!
WARNING
To reduce the risk of personal injury
and property damage, NEVER extend
boom extension beyond leg exten-
sion. Never work under loaded crane
or engine stand.
