5. ホースを接続する
Connect the suction hose to the pump's inlet port (often color-coded, e.g., blue for inlet). Attach the strainer to the end of the suction hose. Connect the discharge hose to the pump's outlet port (often color-coded, e.g., green for outlet). Ensure all connections are tight to prevent air leaks, which can affect priming and pump performance.

6. ポンプのプライミング
The Generac 6821 features a custom funnel design for quick and easy priming. Remove the prime cap located on top of the pump housing. Fill the pump housing with clean water until it overflows. Replace the prime cap securely. The pump must be primed before each use to ensure it can draw water effectively.

操作手順
1. エンジンの始動
- Ensure the pump is properly primed and all hoses are connected.
- Place the suction hose with the strainer into the water source.
- 燃料バルブを「ON」の位置に回します。
- チョーク レバーを「CHOKE」の位置に移動します (エンジンが冷えている場合)。
- エンジンスイッチを「ON」の位置に回します。
- エンジンが始動するまで、リコイルスターターハンドルをしっかりと滑らかに引きます。
- エンジンが始動したら、チョークレバーを徐々に「RUN」の位置に動かします。
2. 操作中
Monitor the pump for consistent water flow and listen for any unusual noises. Ensure the suction hose remains submerged in water to prevent the pump from running dry, which can cause damage.
3.エンジンの停止

- 燃料バルブを「OFF」の位置に回します。
- Allow the engine to cool before handling or storing.
メンテナンス
定期的なメンテナンスにより、最適なパフォーマンスが確保され、ポンプの寿命が延びます。
エンジンオイル
毎回使用前にエンジンオイルの量を確認してください。最初の5時間運転後、その後は50時間ごと、または1年ごとのいずれか早い方でオイルを交換してください。
エアフィルター
Inspect the air filter regularly and clean or replace it as needed, especially when operating in dusty conditions.
スパークプラグ
Inspect the spark plug annually or every 100 hours. Clean or replace if necessary, ensuring the correct gap.
Pump Housing and Impeller
Periodically inspect the pump housing and impeller for debris or wear. Clean out any blockages to maintain efficient flow.
ストレージ
For long-term storage, drain the fuel tank and carburetor. Remove the spark plug and pour a small amount of engine oil into the cylinder, then pull the recoil starter a few times to distribute the oil. Clean the exterior of the pump and store it in a dry, protected area.
