When operating the machine in a work site where asbestos might be present, be sure to operate the machine from the upwind side and wear a mask rated to prevent the inhalation of asbestos. Keep bystanders out of the work site during op- eration. Asbestos might be present in imitation parts. Use only genuine Hitachi Parts. SA-029 PREVENT BATTERY EXPLOSIONS Battery gas can explode.

Do not charge a frozen battery; it may explode. Warm the battery to 16 ° C (60 ° F) first. Do not continue to use or charge the battery when electrolyte level is lower than specified. Explosion of the battery may result. Loose terminals may produce sparks. Securely tighten all terminals. Battery electrolyte is poisonous. If the battery should explode, battery electrolyte may be splashed into eyes, possibly resulting in blindness. Be sure to wear eye protection when checking electrolyte specific gravity.
