5. If the batteries break open and electrolyte
(dilute sulfuric acid) contacts skin or clothing,
wash immediately with running water. If elec-
trolyte gets into your eyes, rinse them out with
clear water and seek medical attention right
away.
6. As service life of the batteries ends, their
capacity and operation time decrease. Contact
your nearest Makita Service Center or Dis-
tributor to replace them with new batteries.
7. When replacing batteries, all batteries should
be replaced at the same time. Mixing fresh and
discharged batteries could increase internal
cell pressure and rupture the discharged bat-
tery.
8. When inserting batteries into this product, the
proper polarity or direction must be observed.
Reverse direction of batteries can result in
leakage or explosion.
9. Never expose mower or batteries to flames,
fire or great heat. Breakage may cause release
of injurious material.
TIPS FOR MAINTAINING MAXIMUM RUN
PERFORMANCE AND BATTERY LIFE
1. Charge the mower immediately after pur-
chase.
2. Always recharge the mower after each use
without fail.
3. We recommend that you leave the charger
connected to the mower even after the charg-
ing cycle is complete. The charger will switch
into its ''maintenance charge (trickle charge)''
mode and keep the battery fresh and fully
charged.
4. Be sure to charge the mower every six months
when it is left uncharged for long periods. If
you fail to do so, the mower may become
unchargeable.
