The battery is capable of exploding. A battery presents a risk of electrical shock and high short circuit current. The following precautions are to be observed when working on batteries: • Remove the 7.5A and 15A fuses from the generator control panel. • Remove watches, rings or other metal objects; • Use tools with insulated handles; • Wear rubber gloves and boots; • Do not lay tools or metal parts on top of the battery; and • Disconnect charging source prior to connecting or disconnecting battery terminals. Do not open or mutilate the battery. Released electrolyte has been known to be harmful to the skin and eyes, and to be toxic. The electrolyte is a dilute sulfuric acid that is harmful to the skin and eyes. It is electrically conductive and corrosive. The following procedures are to be observed: • Wear full eye protection and protective clothing; • Where electrolyte contacts the skin, wash it off immediately with water; • Where electrolyte contacts the eyes, flush thoroughly and immediately with water and seek medical attention; and • Spilled electrolyte is to be washed down with an acid neutralizing agent. A common practice is to use a solution of 1 pound (500 grams) bicarbonate of soda to 1 gallon (4 liters) of water. The bicarbonate of soda solution is to be added until the evidence of reaction (foaming) has ceased. The resulting liquid is to be flushed with water and the area dried. 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 the battery; • DO NOT cause flame or spark in battery area; and • Discharge static electricity from body before touching the battery by first touching a grounded metal surface. Be sure the AUTO/OFF/MANUAL switch is set to the OFF position before connecting the battery cables. If the switch is set to AUTO or MANUAL, the generator can crank and start as soon as the battery cables are connected. Be sure the utility power supply is turned off and the 7.5A and 15A fuses are removed from the generator control panel, or sparking may occur at the battery posts as the cables are attached and cause an explosion. 3.8 COOLING SYSTEM Air inlet and outlet openings in the generator compartment must be open and unobstructed for continued proper operation. This includes such obstructions as high grass, weeds, brush, leaves and snow. Without sufficient cooling and ventilating air flow, the engine/generator quickly overheats, which causes it to quickly shut down. (See Figure 3.8 for vent locations.) ! ! ! DANGER Section 3 — Maintenance Bryant Air-cooled 7 kW, 12 kW and 15 kW Generators SET PLUG GAP AT 0.76 mm (.030 inch) - 7 kW 0.508 mm (.020 inch) - 12 kW & 15 kW MAINTENENANCE 16 Bryant Figure 3.8 – Cooling Vent Locations The exhaust from this product gets extremely hot and remains hot after shutdown. High grass, weeds, brush, leaves, etc. must remain clear of the exhaust. Such materials may ignite and burn from the heat of the exhaust system. The maximum ambient temperature for the generator is 40° C (104° F). 3.9 CORROSION PROTECTION Periodically wash and wax the enclosure using automotive type products. Frequent washing is recommended in salt water/coastal areas. Periodically spray all engine linkage parts and brackets with corrosion inhibiting spray such as WD-40 or a comparable product. 3.10 ATTENTION AFTER SUBMERSION If the generator has been submerged in water, it must not be started and operated. Following any submersion in water, have a Bryant Dealer thoroughly clean and dry the generator. 3.11 OUT OF SERVICE PROCEDURE 3.11.1 REMOVAL FROM SERVICE If the generator cannot be exercised every seven days, and will be out of service longer than 90 days, prepare the generator for storage as follows: 1. Start the engine and let it warm up. 2. Close the fuel shutoff valve in the fuel supply line and allow the unit to shut down. 3. Once the unit has shut down, it will signal a low oil fault. 4. Set the generator’s main circuit breaker to its OFF (or open) position. 5. Set the AUTO/OFF/MANUAL switch to OFF and turn off the utility power to the transfer switch. Remove the 7.5A and 15A fuses from the generator control panel. Disconnect the battery cables as outlined in “General Hazards” (page 2). Turn on the utility power supply to the transfer switch in order to power the emergency load centers circuits while utility power is available. 6. While the engine is still warm from running, drain the oil completely. Refill the crankcase with oil. See ”Engine Oil Recommendations,” Section 3.3.1. 7. Attach a tag to the engine indicating the viscosity and classification of the oil in the crankcase. 8. Remove the spark plug(s) and spray fogging agent into the spark plug(s) threaded openings. Reinstall and tighten the spark plug(s). 9. Remove the battery and store it in a cool, dry room on a wooden board. Never store the battery on any concrete or earthen floor. 10. Clean and wipe the entire generator. 3.11...
