DANGER
Jump starting a weak battery that is cracked,
frozen, has low electrolyte level, or an
open/shorted battery cell, can cause an
explosion resulting in serious personal injury.
Do Not jump start a weak battery if these
conditions exist.
2. Make sure the booster is a good and fully charged
lead acid battery at 12.6 volts or greater. Use
properly sized jumper cables (4 to 6 AWG) with
short lengths to reduce voltage drop between
systems. Make sure the cables are color coded or
labeled for the correct polarity.
CAUTION
Connecting the jumper cables incorrectly
(wrong polarity) can immediately damage
the electrical system.
Be certain of battery terminal polarity and
jumper cable polarity when hooking up
batteries.
Note: The following instructions are from the
SAE J1494 Rev. Dec. 2001 – Battery Booster
Cables – Surface Vehicle Recommended Practice
(SAE – Society of Automotive Engineers).
WARNING
Batteries contain acid and produce explosive
gases.
SHIELD THE EYES AND FACE FROM
THE BATTERIES AT ALL TIMES.
Note: Be sure the vent caps are tight and level.
Place a damp cloth, if available, over any vent
caps on both batteries. Be sure the vehicles do
not touch and that both electrical systems are off
and at the same voltage. These instructions are
for negative ground systems only.
3. Connect the positive (+) cable to the positive (+)
terminal of the discharged battery that is wired to
the starter or solenoid as shown in Figure 18.

4. Connect the other end of the positive cable to the
positive terminal of the booster battery.
5. Connect the black negative (–) cable to the other
terminal (negative) of the booster battery.
6. MAKE THE FINAL CONNECTION ON
THE ENGINE BLOCK OF THE STALLED
VEHICLE (NOT TO THE NEGATIVE POST)
AWAY FROM THE BATTERY. STAND BACK.
7. Start the vehicle and remove the cables in the
reverse order of connection (the engine block
(black) connection is the rst to disconnect).
Check Mower Blades
Service Interval: Before each use or daily
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Lift deck and secure in raised position as stated in
the Clean Grass Build-Up Under Deck section.
3. Inspect blades and sharpen or replace as required.
4. Reinstall the blades (if they were removed) in the
following order:
A. Install the blade onto the spindle shaft.
