Connecting A Battery; Battery Safety Instructions - DeWalt DXCMH1393075 Instruction Manual

Connecting a Battery

1. Battery: A 12 volt sealed battery with a minimum ampere-
hour rating of 18 Ah is required (battery not included).
2. Battery cables: Select battery cables to avoid greater than
.05 volt drop in the cable during starter motor operation.
3. Battery Cable size and length: (Gauge x length)
Positive Cable: AWG No. 4 x 1.5 m (5.0 ft) maximum.
Negative Cable: AWG No. 4 x 2.3 m (7.5 ft) maximum.
4. Wiring Precautions:
A. Connect the battery positive (+) cable to the starter
solenoid terminal.
B. Connect the battery negative (-) cable to the engine
crankcase or engine frame mounting bolt.
C. Do not route the battery cables on or near any hot,
moving or rotating parts or sharp edges. Keep the
battery cables and electrical wires away from the fuel
line.
D. Protect positive electrical connections with a cover or
insulation.
Failure to connect and disconnect in the proper sequence can
cause equipment damage. Ensure there is a clean tight fit from the
cables to the post.
WARNING: Remove the cable from the negative (-) side of
thebattery before servicing.
Servicing of batteries are to be performed or supervised by person-
nel knowledgeable of batteries and the required precautions. Keep
unauthorized personnel away from batteries.

Battery Safety Instructions

WARNING: Lead-acid batteries present a risk of fire because
they generate hydrogen gas. The following procedures are to be
followed:
• Do not smoke when near batteries.
• Do not cause flame or spark in battery area.
• Discharge static electricity from body before touching
batteries by first touching a grounded metal surface.
• Do not dispose of batteries in a fire. The battery is
capable
of exploding.
• Do not open or mutilate the battery or batteries.
Released electrolyte has been known to be harmful to
the skin and eyes and to be toxic.
WARNING: A battery presents a risk of electrical shock and
a high short circuit current. The following precautions are to be
observed when working on batteries:
• Remove watches, rings or other metal objects.
• Use tools with insulated handles.
• Wear rubber gloves.
• Do not lay tools or metal parts on top of batteries.
• Disconnect charging source prior to connecting or
disconnecting battery terminals.
• Determine if the battery is inadvertently grounded. When
inadvertently grounded, remove source of ground.
Contact with any part of a grounded battery is capable of
resulting in electrical shock. The risk of such shock is
reduced when such grounds are removed during
installation and maintenance.
• Failure to connect and disconnect in the proper sequence
can cause equipment damage. Ensure there is a clean
tight fit from the cables to the post.
