使用說明
一、 操作說明
1. 檢查泵浦與馬達/引擎的每個扣件，是否穩固的鎖緊於架上。
2. 將吸水管接於泵浦進水口鎖緊，並將高壓管接於出水口。
3. 將吸水管(網)放入蓄水槽內並保持水管暢通。吸水過濾網需放置水槽底部上方 20
公分處，預防吸進底部泥沙，確保泵浦壽命，吸水管給水量需大於泵浦使用水量，
如此才能達到使用壓力。
4. 檢查馬達電源是否配接正確電壓；引擎燃料是否正確、充足。
5. 初次啟動泵浦後，請先將泵浦內空氣排出後，停止泵浦。
6. 壓力調整:調整時請依照壓力錶顯示之壓力為參考值，壓力調整弁加壓以順時針方
向調整;反之，以逆時針方向調整。調整壓力時需要打開噴槍;最高壓力不得高於泵
浦設定之壓力，以維護機器壽命。
7. 使用完時，請先關閉動力來源(馬達/引擎)再作動噴槍一次，避免壓力蓄存於高壓
管中。
二、 泵浦的潤滑
1. 更換機油時，請將泵浦停止作動，並注意油溫，請冷卻後再進行更換。
2. 初次使用 100 小時應更換機油，以後每使用 300 小時應更換一次。
3. 更換機油時，請旋開洩油螺絲排出骯髒的機油。
4. 將洩油螺絲鎖緊後，打開加油蓋注入#30~#40 之車輛用重型機油，機油應保持在
油鏡 2/3 的位置。
三、 特別注意事項
1. 使用自來水作為泵浦的水源。
2. 馬達電源線若要延長時，請依馬力值所需大小法規延長。
3. 確實的更換機油以保持泵浦的潤滑，降低機械損耗。
4. 泵浦與吸水網之高度差(揚程)請勿超過 1.3 公尺。
5. 水溫請勿超過攝氏 60 度。
6. 若使用的水源加入藥劑、肥皂或其他物質，請在使用完畢後以清水沖洗泵浦內部
一分鐘，以延長泵浦的使用壽命。
7. 泵浦的轉速/壓力不得超出建議轉速/壓力的最高值。
8. 請確定馬達/引擎的動力可以配合泵浦。

Operation Instructions
A. Operating Instructions
1. Check every fastener to make sure that the pump and engine/motor are installed
firmly onto the frame.
2. Connect the suction hose to the Water Inlet of the pump and secure the hose;
connect the high pressure hose to the Water Outlet.
3. Put the suction hose (with filter) into the water tank and make sure that water
flows smoothly. Please suspend the suction filter around 20cm above the bottom
of the water tank to avoid suctioning residue which might reduce the product’s
life.
4. Check if the motor is connected to the right voltage; check if the engine fuel is
suitable and sufficient.
5. Always release air from the pump when first starting it.
6. Pressure adjustment:
◇Check the pressure displayed on Pressure Gauge for reference when adjusting it.
◇The maximum pressure should not exceed the pump’s working pressure.
◇Hold the spray gun trigger when adjusting the pressure.
◇Turn the knob clockwise to increase pressure; counterclockwise decrease.
7. When finished using the pump, turn off the power of motor or engine and
squeeze the spray gun trigger again to release the pressure stored in the high
pressure hose.
B. Oil Change
1. Replace the oil in the pump after the first 100 hours of use. After this, the oil
should be changed after every 300 hours of use.
2. Unscrew the Oil Drainage Screw and drain the oil from the pump.
3. Tighten the Oil Drainage Screw before refilling with clean motor oil SAE
#30~#40 up to the level of 2/3 of the Oil Window.
※Attention: When replacing the oil, please turn off the product and
make sure that the oil temperature has cooled before replacing.

物理 WU LI ─WH-3520F, WH-3523F, WH-3526F (2021V) 5
C. Reminders
1. Always use clean water with the product.
2. If using an extension cord, please follow the electrical regulations and select the
appropriate power cord diameter.
3. Be sure to change the oil according to the Oil Change section or the pump might
be damaged.
4. The pump’s location should be no more than 1.3 meters higher than the suction
filter.
5. The water temperature should not exceed 60℃.
6. If using water containing chemicals, detergents or other substances, please run
the pump with clean water for one minute after use to prolong its service life.
7. The pump’s revolution and working pressure should not exceed the maximum
suggested values.
8. Please make sure the motor or engine power is suitable for the pump.
