5. Proceed to start the machine. If it does not start
immediately, start the jumper vehicle engine to
avoid excessive drain on the booster battery.
6. After the machine is started and running smooth-
ly, have the second person remove the jumper
cables (negative (-) jumper cable first) from the
jumper vehicle battery, and then from the disabled
machine while being careful not to short the two
cables together.
Allow sufficient time for the alternator to buildup a
charge in the battery before attempting to operate the
machine or shutting off the engine.
NOTE: If the battery frequently becomes dis-
charged, have the battery checked for possible
dead cells, or troubleshoot the electrical system
for possible short circuits or damaged wire insula-
tion.
CHECKING AND TORQUING BOOM LEAF
CHAINS
Inspect the leaf chains for wear and proper tension. On
the three-section boom, two of the chains are on the top
front of the boom. A third chain is accessible from
inside the rear of the boom (see three-section boom
illustration below).
On the four-section boom, three chains are on the top
front of the boom. A fourth and fifth chains are acces-
sible from the rear of the boom (see four-section boom
illustration on next page).
Run the boom out slowly to inspect. Conditions to look
for include cracked or broken plates, protruding or
turned pins, and excessive wear. With a steel tape,
measure 16 links of the strand that flexes over the
sheaves. If the section measures 12.375” (314 mm) or
more, the chain should be replaced. DO NOT repair
sections of a chain. Replace the complete chain.
IMPORTANT: BE SURE that the jumper battery is
also a 12-volt D. C. battery, and the vehicle used
for jump starting has a negative ground electrical
system.
1. Turn the keyswitches on both units to OFF. Be
sure that both units are in “Neutral” and NOT
touching.
2. Connect one end of the positive (+) jumper cable
to the positive (+) battery terminal on the disabled
machine first. DO NOT allow the jumper’s posi-
tive (+) cable clamps to touch any metal other
than the positive (+) battery terminals. Connect
the other end of the positive (+) jumper cable to
the jumper battery positive (+) terminal.
3. Connect one end of the negative (-) jumper cable
to the jumper battery negative (-) terminal.
4. Make the final negative (-) jumper cable connec-
tion to the disabled Telescopic Handler’s engine
block or frame (ground) ⎯ NOT to the discharged
battery’s negative (-) post. If making the connec-
tion to the engine, keep the jumper clamp away
from the battery, fuel lines, and moving parts.
NOTE: Twist the jumper cable clamps on the bat-
tery terminals to ensure a good electrical connec-
tion.
WARNING
The ONLY safe method for jump-starting a dis-
charged battery is for TWO PEOPLE to per-
form the following procedure. The second per-
son is needed for removing the jumper cables,
so that the operator does not have to leave the
operator’s compartment while the engine is
running. NEVER make the jumper cable con-
nections directly to the starter solenoid of
either engine. DO NOT start the engine from
any position other than the operator’s seat,
and then ONLY after being sure all controls
are in “neutral”.
Closely follow the jump-start procedures, in
the order listed, to avoid personal injury. In
addition, wear safety glasses to protect your
eyes, and avoid leaning over the batteries
while jump-starting.
DO NOT attempt to jump-start the machine if
the battery is frozen, because this may cause
it to rupture or explode.
