14814548 Mercury SPARK PLUG (NGK#BPZ8HS-10-CAN./BEL.) 6/8/9.9 H.P.

Ether
The ether warning label applies to engines that are equipped with an inlet manifold heater.
The ether warning label is located at the combustion air inlet.
This engine has an inlet manifold heater for cold weather starting. Do not use other types of starting aids such as ether. Such use could result in an explosion and personal injury.
General Hazard Information
Attach a DO NOT OPERATE or similar warning tag to the ignition key switch before performing maintenance or repairing the truck engine. These tags, SEHS7332, are available from your Caterpillar dealer.Do not allow unauthorized personnel on, around or in the truck when maintenance or repair is being performed.* Tampering with the engine installation or the truck OEM wiring installation can be dangerous and could result in personal injury or death and/or engine damage.* When operating the engine in an enclosed area, vent the exhaust to the outside.* If the engine is not running, do NOT release the secondary or parking brake systems unless the truck is blocked or restrained.* Wear a hard hat, protective glasses, hearing protection and other protective equipment as required by job conditions.* Do not wear loose clothing or jewelry that can catch on controls or other parts of the engine.* Make certain that all protective guards and covers are secured in place.* Never put maintenace fluids into glass containers since glass containers can break.* Report all needed repairs.* Stop the engine.* Ensure the protective locks or controls are in the applied position.* Engage the secondary (emergency) or parking brakes.* Block or restrain the vehicle before performing maintenance or repair.* Disconnect the batteries whenever performing any maintenance or before servicing the electrical system.* Do NOT attempt repairs you do not understand.* When starting an engine after repairs have been made to the fuel system or governor, make provisions for shutting off the engine's inlet air and/or fuel supply (to stop the engine), in case there is an overspeed on start-up.* Start the engine only from the operator's station (cab). Never short across the starter terminals or the batteries as this could bypass the engine neutral start system as well as damage the electrical system.Pressure Air and Water
Pressure air can cause personal injury. When using pressure air for cleaning, wear a protective face shield, protective clothing and protective shoes. Pressurized water could cause debris and/or hot water to be blown and result in personal injury. The maximum air pressure must be below 205 kPa (30 psi) for cleaning purposes.Air Compressor Pressure Relief Valve
If the air compressor pressure relief valve mounted in the air compressor cylinder head is bypassing compressed air, there is a malfunction in the air system, possibly ice blockage. Under these conditions, your truck may have insufficient air for normal brake operation.Do not operate the truck until the reason for the air bypass is identified and corrected. Failure to heed this warning could lead to property damage, personal injury, or death to the truck driver or bystanders.Fluid Penetration
Always use a board or cardboard protector when checking for a leak. Escaping fluid under pressure, even a pin-hole size leak, can penetrate body tissue, causing serious injury or possible death. If fluid is injected into your skin, it must be treated by a doctor familiar with this type of injury immediately.Fluid Spillage Containment
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the engine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to NENG2500, Tools And Shop Products Guide, for tools and supplies suitable to collect and contain fluids in Caterpillar products. Dispose fluids according to local regulations and mandates.Asbestos Information
This Caterpillar product and replacement parts shipped from the factory are asbestos free. Caterpillar recommends the use of only genuine Caterpillar replacement parts.Burn Prevention
Do not touch any part of an operating engine. Allow the engine and components to cool before any repair or maintenance is performed on the engine. Relieve all pressure in air, oil, fuel or cooling systems before any lines, fittings or related items are disconnected or removed.Coolant
To prevent personal injury, do not step up on engine to remove the filler cap, if applicable. Use an adequate ladder. At operating temperature, the engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant. Check the coolant level only after the engine has been stopped and the filler cap is cool enough to remove with your bare hand.Remove the cooling system filler cap slowly to relieve pressure. Allow cooling system components to cool before draining. When pressure is relieved rapidly, this hot coolant water can turn into steam. Any contact with hot water or steam can cause severe burns.Cooling system supplemental additive (conditioner) contains alkali. To prevent personal injury, avoid contact with the skin and eyes and do not drink.Oils
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact the skin.Batteries
Battery electrolyte contains acid and can cause injury. Avoid contact with the skin and eyes. Wash hands after touching batteries and connectors. Use of gloves is recommended. Always wear protective glasses when working with batteries.Batteries give off flammable fumes which can explode. Always thaw a frozen battery before jump starting. Frozen batteries can explode. Do not smoke when observing the battery electrolyte levels.Fire or Explosion Prevention
Determine whether the engine will be operated in an environment in which combustible gases could be drawn through the air inlet system. These gases could cause the engine to overspeed, which in turn could seriously damage the engine and result in bodily injury or property damage. If your application involves the presence of combustible gases, consult your Caterpillar dealer to obtain additional information concerning protection devices suitable for the application involved.If equipped with an air conditioner, do not smoke when servicing, charging or working around air conditioner leaks. Inhaling freon gas through a lit cigarette or other smoking method, or inhaling fumes released from a
