The inlet valve of most Sarome butane gas lighters is equipped with an exhaust system for efficient refilling at low temperatures. Therefore, butane spray back will occur when gas tank is full. Read "How to refill fuel" in Support for further details.
We highly recommend you to use Sarome butane gas. Impure butane gas will clog up your lighter and other brands of butane gas with unknown pressures will affect the performance of the lighter.
Always use Sarome flints. These are sized and hardened for optimum performance for use in Sarome flint lighters. Use of other flints with different size and hardness may damage the spark wheel and may require repair.
A lighter consists of many precision parts and it must be used with the utmost care. When a lighter has been dropped, component parts may damage which causes misfire. Please return for service.
When a lighter is dropped or punctured, packing inside gas tank or inlet valve may probably damage and gas leakage is occurred. When lighter makes hissing sound, do not attempt to ignite but return for service.
There is no specified time limit for butane gas canister. However, metal, rubber and spring parts inside do have a durability limit. Store in a well ventilated area and keep away from oxidizers, heats and flame.
A flint stone is mechanically connected with the type of spark wheel used in the type of lighter taking into consideration of the hardness, thickness and length. Always use flints that manufacturers recommend.
